valence

Question 2

what are the rules of writing a chemical symbol

Answer 2

Question 3

electronic structure of neon
It’s in group 8/0
period 2

Answer 3

10 electrons 2,8 it is a nobel gas

Question 4

explain what happens as you move down the periodic table?

Answer 4

the atoms get larger as you go down the group. the outer electron gets further from the nucleus as you go down the group. the attraction between the nucleus and outer electron gets weaker as you go down the group - so the electron is more easily lost.
It gets more reactive
