Ions - forming Anions and Cations

What is a positive ion called?

• anion

• cation

• isotope

• covalent

What is a negative ion called?

• anion

• cation

• covalent

• isotope

Which types of elements from anions?

• metals

• nonmetals

• metalloids

• noble gases

Why do elements form bonds?

• to get a charge

• so they can make friends

• to become stable by getting a full valence shell

• to become stable by increasing their mass

How many electrons would a Nitrogen (started with 5 electrons in outer shell) ion gain/lose?

• lose 5

• gain 5

• lose 3

• gain 3

How many electrons would a Calcium (started with 2 electrons in outer shell) ion gain/lose?

• lose 1

• gain 1

• lose 2

• gain 2

Why are ions formed?

• To make our lives difficult

• Because atoms want to be stable

• Because atoms have the same number of protons and electrons

• Because atoms gained neutrons

Which particles change the charge in atoms when ions are formed?

• Protons

• Electrons

• Neutrons

Ionic bonds form between two ions that have

• negative charges

• positive charges

• opposite charges
