What are 3 types of bonds that can hold elements together?

Covalent, ionic, metallic

Covalent bonds

Molecule

Between nonmetal and nonmetal

shares valence electrons

have polar and non polar

Polar Covalent

Does not share valence electrons evenly

electronegativity 0.3-1.7

Non polar covalent

Shares valence electrons evenly

electronegativity 0-0.3

What creates dipole?

When electrons are shared unequally between atoms in covalent bond

Ionic compounds

Salts

Between metal and nonmetal

electronegativity 1.7-3.3

What kind of structure is formed when ions are held together?

crystal lattace

What happens to a valence electrons when forming an ionic bond?

Valence electrons transfers completely

Metallic bond

between metal and metal

sea of electrons

metals are good conductors of heat and electricity

malleable allows into shape

ductile allow into wire

Ionic compound

has two kinds binary and ternary

Binary

2 elements

name by metal name + non mental name ide

Ternary

3 elements

at least one polyatomic ion

name by cation then anion

Why does polyatomic ions stay?

already have their own unique endings

Roman numeral

only use on transition metals

Why don’t we use criss cross reduce on covalent bond?

covalent bonds do not have charges.
