Question

Find the elements sodium, oxygen, and phosphorus on the periodic table. Describe the monoatomic ions each would form. Then, given what you know about chemical bonding, describe and give the formulas for the types of ionic compounds they would produce with each other.

Answer 1

What exactly are you having a problem with?

Answer 2

Hello and welcome to OpenStudy. Have you managed to locate them in the periodic table? Please note their position in terms of row and column.

Answer 3

Having problems reading the periodic table. So far I got Na20, Na3P, P40, ect. Still not sure how I am suppose to answer my questions. I am terrible at chemistry

Answer 4

Don't be so down on yourself I'm sure you aren't bad at chemistry! Just give it and attention and you will eventually get it.

Answer 5

Do you want me to go over the organization of the periodic table with you?

Answer 7

So each element is numbered based on the number of protons it contains, the number of protons an atom contains identifies what element it is and what its properties are

Answer 8

So number 1 on the periodic table is hydrogen as it contains 1 proton

Answer 9

Number 2 is Helium it contains 2 protons, and it keeps going like that

Answer 10

I will label a periodic table for you, one second

Answer 11

Thank you so much for helping me.

Answer 12

The table you had be go to is great. Thank you

Answer 13

I'm looking at the chart you just sent me.

Answer 14

It is important to know that nucleus's contain protons (which dictates the elements identites and have a charge of +1 as well as having a mass of 1 amu) and sometimes neutrons, which have a neutral charge and a mass of 1 amu.

The weight of neutrons and protons in a molecule come into play when you look at the molecular mass.

If you look at the molecular mass of hydrogen you should see that it is about 1.0079g/mol
which might seem confusing because hydrogens just contain one proton so shouldn't there molecualr mass be equal to 1g/mol not 1.0079g/mol ? The reason it is 1.0079g/mol is because there exists a hydrogen atom in nature that contains a neutron in its nucleus (this is called deuterium)! They call these isotopes, so deuterium is an isotope of hydrogen, and it has a molecular mass of 2g/mol. Since the molecular mass on the periodic table is based on the average prevlance of isotopes in the environment (there is very little deuterium in the environment) we have a molecular mass of 1.0079g/mol

Answer 15

I'm just covering pretty much everything you need to know about the periodic table unless you dont want me to

Answer 16

Electrons have a very very very very very tiny mass so we dont use them count them in the molecular mass calculation normally. Electrons have a charge of -1. For an atom to be neutral it has to have a neutron for every proton.

So hydrogen having 1 proton is neutral when it has 1 electron, it has a charge of -1 when it has 2 electrons, and a charge of +1 when it has no electrons

Answer 17

Now there is this thing called the octet rule (although it is a rule that is often broken in chemistry, but lets keep things simple), where atoms want to have 8 electrons (this mostly applies to the first 18 elements on the periodic table).

First though I should seperate the perodic table into larger categories, I will keep it simple and say that anything in columns 3B-2B these are transition metals and they are strange so ignore them sort of kind of for now! you should only really focus on 1A-8A

Answer 18

So group 8A is called the noble gases and they are typically unreactive (although they can be reactive under exotic conditions), they contain 8 valance electrons and thus fulfill the octet rule.

Answer 19

Valance electrons being the electrons that you can sort of think of being father away from the nucleus they are more reactive

Answer 20

to learn the basics, i prefer you watch khan academy videos, here is the link.
https://www.khanacademy.org/science/chemistry

Answer 21

You can count the number of valance electrons pretty easily for an atom based on what group they are in.

For instance,

Lithium (Li) has 1 valance electron
Beryllium (Be) has 2 valance electrons
Boron (B) has 3 valance electrons
Fluorine (F) has 7 valance electrons
Sodium (Na) has 1 valance electron
etc...

The octet rule basically states that atoms want to be more like the noble gas they are closest to.

So Lithium will readily give up its 1 electron so it can be more like helium, Boron will give up its 3 electrons as well to be more like helium

Fluorine will want an electron so it can be more like Neon, sodium will give up an electron to be more like Neon as well.

Group 4A elements like Carbon are interesting because they can go both ways

Answer 22

Khan academy is also a good source

Answer 23

and be easy on my friend, don't make him type so much.

Answer 24

if you dont want to read the novel I wrote

Answer 25

I dont mind, if the person has any questions I can always answer them

Answer 26

you are a good guy....so nice of you. I prefer let her watch the videos and if she still needs help we are always here.....

Answer 27

Elements in Groups 1A-2A form ionic bonds, which is essentially an exchange of electrons, for instance

NaCl, sodium gives one electron to chlorine, so we have Na+ and Cl- they are both happy because they are like the noble gases they want to be!

Elements in 3A-7A
Form covalent bonds which is a sharing of electrons (this sharing is not always equal it is dependent on electronegativity of the elements (you can look that up it is a trend in the periodic table))

So for instance,

NO Nitrogen and oxygen share electrons making them have each 8 electrons so they fulfill the octet rule and are like noble gases

Answer 28

Meh smeh I pretty much explained everything she needs to know already lol

Answer 29

Do you follow?

Answer 30

monoatomic ions, an ion is just an atom with a charge, mono means one.

So an ion is just an atom or molecule that has a charge as I explained above,

"So hydrogen having 1 proton is neutral when it has 1 electron, it has a charge of -1 when it has 2 electrons, and a charge of +1 when it has no electrons"

A Hydrogen with two electrons would be an ion as it has a charge of -1, another example would be a hydrogen with no electrons as it would have a charge of +1 these are both examples of ions!

Answer 31

just as an aside Hydrogen is an exception to the ionic bond rule I gave you! it can form covalent bonds.

Answer 32

can someone please help me with my question

Answer 33

I just posted in your question

Answer 34

I really want to thank you so much for your help. I'm a little confused right now and will have to study everything you wrote to me. I can't say enough how much I appreciate this help. Give me a day or so to study what you explain please. I just had to run out and now I'm back but am very sick with a horrible virus. I will definately come back to this site for help. I'm really behind in my Science class because I save it for last since I'm so horrible at science (I'm in the arts field as in dance, music) and math. Again thank you!

Answer 35

No problem, you can't be horrible at science, you just need to give it more of your attention.
