Ionic Bond Part 1

What are ionic bonds?

• valence electrons transferred between atoms

• valence electrons are shared between atoms

Why do ionic bonds form?

• so the number of protons equals the number of electrons

• to follow the octet rule and make sure each atom has a full outer energy level

• so an atom can become unstable

An atom that has gained or lost electrons is called ...

• a new element

• an isotope
• an ion
• a neutral atom

if METALS are more likely to LOSE electrons, they will form ...

• anions

• neutral atoms

• cations

If an oxygen atom has 8 protons (+) and 10 electrons (-), what is it's charge?

• O^-10

• O⁺⁸

• O^-2

• O⁺¹⁰

If an aluminum atom has 13 protons (+) and 10 electrons (-), what is it's charge?

• Al⁺³

• Al⁺¹³

• Al⁺¹⁰

• Al^-10

ionic bonds form between

• a metal and nonmetal

• two nonmetals

• two metals

What is the total charge of an ionic compound?

• positive

• negative

• neutral

if NONMETALS are more likely to GAIN electrons, they will form ...

• anions

• neutral atoms

• cations
