22
Q

Ionic bond

A

Chemical bonds occurring between ions of opposing charges. Occurs between metals and nonmetals

23
Q

Ionic lattice

A

Ionic solids exist as a large, ordered, three dimensional network of positively and negatively charged ions
Ions are arranged so that positive ions are adjacent to and in contact with the negative ions
Ions with like charges repel one another

24
Q

Lattice energy

A

Stronger when the charges are larger based on coulumbs’ law
Example: MgO has stronger lattice energy than NaCl

25
Q

Molecule

A

Collection of atoms bound together
Example: oxygen gas O2

26
Q

Molecular substance

A

Any substance composed of distinct molecules

27
Q

Covalent bonds

A

Bonding that occurs between electrons in one
atom and the nucleus of another atom
Occurs between nonmetals

28
Q

Electronegativity (EN)

A

Determines if electrons are shared or transferred when a bond is formed
Greater the EN value, the more likely electrons will be drawn to an atom

29
Q

Polar covalent bond

A

Unequal electron sharing
