Question

The elements listed at the far left side of the periodic table are _____.

metals
nonmetals
transition metals
metalloids
i have no idea @taramgrant0543664

Answer 1

Non-metals are the gases which are found on the right side of the table
Transition metals are what you see in the middle of the table
Metalloids are what you find between the transition metals and the non metals so they are more on the right side
Metals are found on the left side due to their properties

Answer 2

alright thanks this is a science pretest that has 54 questions some i know some i don't

Answer 3

im on question 17 uhhhhhh i have to go to work in an hour too

Answer 4

Well I can definitely check it over for you, and I have to go soon too but we can get through as many as we can

Answer 5

alright thanks

Answer 6

should i just post the questions in here?

Answer 7

Ya you can or you can make new posts doesn't matter

Answer 8

A solution

has a uniform composition and is able to be separated by physical means.
has a heterogeneous composition and is able to be separated by physical means.
has a heterogeneous composition and is able to be separated by chemical means.
has a uniform composition and is able to be separated by chemical means.

Answer 9

b?

Answer 10

A solution - you can evaporate the solvent and obtain the soluted substance.

A heterogenous mixture is obviously not uniform, so it's not a possible answer.
An element is the simplest building block of substances that carries chemical properties. You can only convert elements through nuclear reactions.
A compound is made of atoms bound together through chemical bonds. Physical methods can't break it apart.
So I would go with a

Answer 11

thank ya

Answer 12

What is the relationship between a compound and the elements it is made from?

The compound takes on a mixture of properties from the elements.
The compound takes on the properties of the stronger element.
The compound may have properties that are very different from those of the elements.
The compound may have the properties of the most abundant element in the compound.

Answer 13

Sorry it would definitely be C

Answer 14

What is the name of the scientist who first developed the periodic table?

Bohr
Dalton
Mendeleev
Chadwick
ummmm i know its not dalton

Answer 15

Nope that would be mendeleev

Answer 16

thanks

Answer 17

question 31

Answer 18

Which of the following is not a property of a metal?

Luster
Malleability
Permeability
Ductility

Answer 19

a

Answer 20

They are not permeable. Metals are sonorous, ductile: Can be stretched into wires, Malleable: can alter shape easily as the atoms have only delocalised electrons, allowing for layers to slide over each other. As for luster, only most refined metals are lustrous. Most metals exist in compounds, with only unreactive ones like gold and platinum existing as an element.

Answer 21

thanks i would have gotin that wrong

Answer 22

Well now you know lol

Answer 23

As you move from left to right on the periodic table, the atomic number _____.

increases
decreases
stays the same
changes randomly
a?

Answer 24

Yes it would be A

Answer 25

question 40
Thomson proposed that

the atom is mostly solid space.
the electrons are spread through a solid, positive nucleus.
the electrons orbit around the nucleus.
atoms are the smallest particle.

Answer 26

Thomas proposed that 'Plum Pudding Model' for the electrons configured around the atom, showing that the electrons are spread through a solid, positive nucleus.

Answer 27

well that's interesting

Answer 28

im not being sarcastic that's actually pretty cool

Answer 29

Each different model is interesting and how when the model changes what they figured out

Answer 30

A substance that has a uniform composition and is able to be separated by physical means is a(n) ____.

solution
heterogeneous mixture
element
compound

Answer 31

It would be a solution

Answer 32

okay almost done question 46

Answer 33

Let's do it!

Answer 34

okay i knew that one so 47

Answer 35

Ionic bonding involves

atoms sharing electrons.
the metal atom losing electrons to the nonmetal atom.
two nonmetal atoms transferring electrons.
two metals transferring electrons.

Answer 36

In ionic bonding the metal gives up electrons and the nonmetal takes electrons so B

Answer 37

When a nonmetal bonds with a nonmetal, they form a(n) ____.

solution
ionic compound
covalent compound
element

Answer 38

Well we just talked about ionic bonds so we know it's not that, when non metals bond it's two elements making something so they don't make a new element
They are referred to as a colvalent compound

Answer 39

Which of the following is not an example of an extensive physical property?

Mass
Length
Size
Density
density?

Answer 40

49

Answer 41

Yes it would be density

Answer 42

last question
Bohr's model of the atom most resembles

plum pudding.
the solar system.
a basketball.
snow.

Answer 43

Thompson was plum pudding model, Bohrs looked like the solar system

Answer 44

thank you ill tell you what i got one sec

Answer 45

81%

Answer 46

That's pretty good still

Answer 47

yeah it is thank you so much i would have flunked it on my own

Answer 48

It's no problem what so ever!

Answer 49

I'm happy to help!!
