1
Increases across a period and decreases down a group
2
Elements in Groups 3-12
3
Increases with each successive electron removed
4
The 1s orbital is filled before the 2s orbital because of this
5
This principle dictates that no two electrons can have identical quantum numbers
6
Calcium is classified as what kind of metal
7
Na+ and Ne are this
8
The elements in the group containing sulfur and selenium are known as
9
Elements with no recorded electronegativity
10
Nitrogen and Hydrogen naturally exist as these kinds of molecules
11
bonds where electrons are shared
12
The most electronegative element
13
Element with the largest atomic radius
14
Liquid metal at room temperature
15
subatomic particles that contribute to the atomic mass
16
Numbers used to describe an electron in an atom
17
Two electrons are required to fill one of these
18
Liquid nonmetal at room temperature
19
This type of ion has a smaller ionic radius than the neutral atom
20
These subatomic particles contribute to an element's atomic number
21
This rule is why orbitals are half-filled before they are completely filled
22
bonds where electrons are transferred
23
unreactive
24
Atoms that are bonding strive to have a full this
