Question 0

Isoelectronic

Answer 0

Having the same number of electrons per atom, ion or molecule

Question 1

Ionic bond

Answer 1

The electrostatic attraction between oppositely charged ions

Question 2

Covalent bond

Answer 2

A chemical bond in which atoms share the bonding electrons.

Question 3

Bonding electron pair

Answer 3

An electron pair that is involved in bonding. Found in the space between two atoms.

Question 4

Lewis structure

Answer 4

A diagram that represents an arrangement of covalent electrons and bonds in a molecule or polyatomic ion.

Question 5

Duet Rule

Answer 5

The observation that the complete outer shell of valence electrons when hydrogen and period 2 metals are involved in bonding.

Question 6

Octet rule

Answer 6

The observation that many atoms tend to form the most stable substances when they are surrounded by 8 electrons in their valence shells

Question 7

Lone electron pair

Answer 7

A pair of valence electrons that is localized to a given atom but not involved in bonding

Question 8

Simplified Lewis structure

Answer 8

A lewis structure in which bonding electron pairs are represented by solid lines and lone electron pairs by dots.

Question 9

Space-filling model

Answer 9

A model of a molecule showing the relative sizes of the atoms and their relative orientations

Question 10

Coordinate covalent bond

Answer 10

A covalent bond in which the electrons involved in bonding are from one atom (mooching)
