Chemistry

Question 1

Elements

Answer 1

Each element is an individual type of atom (has unique chemical characteristics)

Question 2

Central Nucleus

Answer 2

Contains most of atomic mass (Contains protons and neutrons)

Question 3

Protons

Answer 3

have a +1 charge

Question 4

Neutrons

Answer 4

Have a 0 charge

Question 5

Outside the nucleus

Answer 5

Electrons (Have a -1 charge)

Question 6

Electrons

Answer 6

Have very little mass in orbitals (Fundamental Particles)

Question 7

Ions

Answer 7

Atoms or molecules with a net charge of ‘+’. or ‘-‘ electrical charge (Some ions lose electrons, some ions gain electrons)

Question 8

Ionic Bonds

Answer 8

Opposites charges attract (an electrostatic attraction)

Question 9

Covalent Bonds

Answer 9

Occur when atoms share electrons

Question 10

Nonpolar covalent bond

Answer 10

Electrons shared equally ( <0.5)

Question 11

Polar covalent bond

Answer 11

Electrons shared unequally ( ≥0.5)

Question 12

Electronegativity

Answer 12

Determines if a covalent bond will be polar or nonpolar

Question 13

Electrical neutral atom

Answer 13

of protons = # of electrons
