Question 0

Diatomic molecule

Answer 0

A molecule containing only 2 atoms

Question 1

Octet rule

Answer 1

Chemical compounds tend to form so that each atom, by gaining, losing, or sharing electrons, has an octet of electrons in its highest energy level

Answer 2

A molecule containing only 1 atom

Question 3

Ionic substance

Answer 3

A substance whose atoms are held together by ionic bonds

Question 4

Salts

Answer 4

An ionic compound comprised is a cation and an anion forming an acid

Question 5

Crystal lattice

Answer 5

The pattern of the atoms or molecules in a crystal

Question 6

Monatomic ion

Answer 6

An ion formed from a single atom

Question 7

Binary compound

Answer 7

A compound composed of 2 different elements

Question 8

Polyatomic ions

Answer 8

A charged group of covalently bonded atoms

Question 9

Covalent bond

Answer 9

A chemical bond resulting from the sharing of an electron pair between 2 atoms

Question 10

Molecular substance

Answer 10

A substance whose atoms are held together by covalent bonds

Question 11

Nonpolar covalent bonds

Answer 11

A covalent bond in which the bonding electrons are shared equally by the bonded atoms resulting in a balanced distribution of electrical charge

Question 12

Polar covalent bond

Answer 12

A covalent bond in which the bonded atoms have an unequal attraction for the shared electron

Question 13

Single covalent bond

Answer 13

A covalent bond produced by the sharing of one pair of electrons between two atoms.

Question 14

Lewis for structure

Answer 14

A formula in which the atomic symbols represent nuclei and inner-shell electrons, dot pairs or dashes between two atomic symbols represent electron pairs in covalent bonds, and dots adjacent to only one atomic symbols represent unshared electrons

Question 15

Double covalent bond

Answer 15

A covalent bond produced by the sharing of 2 pairs of electrons between 2 atoms

Question 16

Triple covalent bond

Answer 16

A covalent bond produced by the sharing of 3 pairs of electrons between 2 atoms

Question 17

Molecular formula

Answer 17

A formula showing the types and numbers of atoms combined in a single molecule of a molecular compound

Question 18

Electronegativity

Answer 18

A measure of the ability of an atom in a chemical compound to attract electrons

Question 19

Symmetrical molecule

Answer 19

A molecule that can be “cut” in half and have the same charge on the ends. It is non polar

Question 20

Asymmetrical molecule

Answer 20

A molecule that can not be “cut” in half because it’s ends have different charges. It is polar

Question 21

Ion

Answer 21

An atom of group of bonded atoms that has a positive or negative charge

Question 22

Metallic bond

Answer 22

A chemical bonding that results from the attraction between metals atoms and the surrounding sea of electrons

Question 23

Exothermic process

Answer 23

A chemical reactor that releases heat energy

Question 24

Endothermic process

Answer 24

A chemical reaction that absorbs heat energy

Intermolecular forces of attraction

Answer 25

The fire of attraction between molecules

Question 26

Dipoles

Answer 26

Equal but opposite charges that are separated by a short distance

Question 27

Hydrogen bonds

Answer 27

The intermolecular force in which a hydrogen atom that is binding to a highly electronegative atom is attracted to an unshared pair of electrons of an electronegative atom in a nearby molecule
