Question

SOMEONE PLEASE HELP WITH CHEMISTRY QUESTION. DRAWING PICTURE NOW. PLEASE!!!

Answer 1

i need help filling in the boxes please!!

Answer 2

atomic number = number of protons
number of electrons = atomic number

atomic mass = number of protons + neutrons

Answer 3

yes I know that but I'm having a hard time with the net charge...its throwing me off

Answer 4

Protons have positive 1 charge and electrons have negative 1 charge.

Answer 5

So, then the number of protons = number of electrons the net charge is 0.

Answer 6

*when

Answer 7

And number of protons * 1 + number of electrons * -1 = net charge

Answer 8

so the furthest one to the right would have 32 electrons

Answer 9

Start with the first column, do one at a time.

Nitrogen has atomic number 7
electrons are also 7, so net charge is 0
Nitrogen has 8 neutrons, so the atomic mass is 15

Answer 10

(Although I haven't done chem in a while)

Answer 11

so that would be the first one with a charge of 0 correct

Answer 12

so its net charge 0 because the protons and electrons are the same?

Answer 13

Yes

Answer 14

You got it!

Answer 15

ok...so the second one would have 78 protons
right?

Answer 16

Yup

Answer 17

Sorry, but I gtg for now. You're doing great!

Answer 18

ok if you get back on I'll probably still need help thnk you!

Answer 19

So, what's the number of neutrons for the 2nd column?

Answer 20

wouldn't it be 117?

Answer 21

because you would subtract 78 from 195

Answer 22

Yes

Answer 23

ok and then there would be 78 electrons as well??

Answer 24

Yes

Answer 25

so would the net charge be 0 again?

Answer 26

Yup

Answer 27

ok the third one is whats confusing me

Answer 28

What is the number of protons?

Answer 29

well its not given...so if the net charge is -3 the number of protons would be 20?

Answer 30

The number of electrons is 18, and the net charge is -3, which means there are 3 more electrons than protons

Answer 31

so 15

Answer 32

Yes

Answer 33

OH YAY. so the element would be P

Answer 34

Phosphorus

Answer 35

Phosphorus, yes

Answer 36

and the fourth column...it would have 32 electrons...same # of protons right?
