How are ions formed ?

Ions are formed when atoms gain or lose electrons

What change do columns 1,2,13,15,16, and 17 take on what charged?

1 has a +1, 2 has +2, 13 has +3, and 15 has -3, 16 has -2 and 17 has -1 charge

What is the octet rule?

The octet rule is when the atom wants 8 valance electrons.

What elements are okay with more/ less than 8 electrons?

Less than 8 is H, He, LI, Be and B. More than 8 electrons are P, S, CL, Br, L,and Xe

What are the three types of bond?

Ionic, Covalent, and Metallic

What is cation?

It is when the atoms lose electrons, which makes an atom positively charged

What is an anions?

Is when the atom gain electrons, which makes an atoms negatively charged

Which elements require a roman numeral when naming and why?

The transition metals since they are many possible charges.

Which elements are the exceptions from the Roman numerals?

Zinc (Zn) and Sliver (Ag). The sometimes is Cadmium (Cd) and is sometimes +2

What is bond polarity?

Describes how equal or unequal electrons are shared between two atoms

How to determine if a bond is polar ?

If it is share equally then it’s nonpolar, and if it’s share unequally then it’s polar
