Question

This diagram is a model of the fluorine atom.



How many electrons, protons, and neutrons are in this atom, and how many additional electrons are needed to completely fill the outer shell of this atom?http://static.k12.com/calms_media/media/1357500_1358000/1357604/1/2312021b226d2fd290d2d7a9f60ac650c38b0572/MS_PHYS_SCI_286730.jpg

Answer 3

Try to figure out what the yellow and white dots represent. That should get you started.

Answer 4

I did, I don't know which color represents which one,

Answer 5

Its either c or d, right?

Answer 6

I'm not going to just give you an answer.

Look at the atomic number of fluorine in a periodic table. That should help you figure out what the yellow and white dots represent.

how is that supposed to help?

Answer 8

what does the atomic number denote?

Answer 9

protons .. now try finding it out
