1.8 Electronic Structures

Question 1

Shell def

Answer 1

An area in an atom, around its nucleus, where electrons are found

Question 2

What energy level is the shell closest to the nucleus

Answer 2

Lowest energy level

Question 3

How many electrons can the first shell hold

Answer 3

2

Question 4

How many electrons can the second shell hold

Answer 4

8

Question 5

How many electrons can the third shell hold

Answer 5

8

Question 6

Electronic structure def

Answer 6

A set of numbers to show the arrangement of electrons in their shells

Question 7

What does the number of electrons in the outermost shell depend on

Answer 7

Group number (except group 0)

Question 8

What does the way an element reacts depend on

Answer 8

The number of electrons in its outermost shell (which is why elements in the same group react in similar ways)

Question 9

Why are noble gases stable and not reactive?

Answer 9

Because they all have 8 electrons in the outer shell (except for helium which has 2)
