A

An anion is a negative ion, an atom that has gained electrons.

19
Q

What type of atoms are usually cations and anions?

Cations are usually metals and anions are non-metals.

20
Q

What is an ionic compound?

A

A compound made up of negatively charged ions and positively charged ions.

21
Q

What is an ionic bond?

A

The attraction that holds the ions together.

22
Q

True

23
Q

Who chooses the names of the elements?

A

The international union of pure and applied chemistry (IUPAC)

24
Q

How do you name ionic compounds?

A

Covalent bonds

36
Q

Why do electrons transfer?

A
  1. the metals hold on the outer electrons is weak
  2. the attraction of the non-metal for the metal’s electrons is strong
  3. a full outer orbit is stable
37
