Part 1

Question 1

Atomic number

Answer 1

Number of protons and electrons

Question 2

Mass number

Answer 2

Total number of protons and neutrons

Question 3

Valence electrons

Answer 3

Electrons farthest from the nucleus

Question 4

Ion

Answer 4

A positive or negative charge to an atom due to a loss or gain of electrons

Question 5

Isotope

Answer 5

Atom with same number of protons but different neutrons

Question 6

Principle quantum number

Answer 6

Designated n. First number

Question 7

Azimuthal quantum number

Answer 7

Second quantum number. Designated L. Tells us the shapes of the electron orbitals

Question 8

Magnetic quantum number

Answer 8

Third quantum number. Tells us orientation of the orbitals

Question 9

Periodic trend for atomic radii

Answer 9

Decreases left to right. Increases down. Largest bottom left

Question 10

Periodic trend for electronnegativity

Answer 10

Increases left to right. Decreases down. Florine more electronegative

Question 11

Type of reaction. S+ o2= so2

Answer 11

Combination reaction

Question 12

2hgo= 2 hg + o2

Answer 12

Decomposition

Question 13

Zn+ cuso4= cu + znso4

Answer 13

Single displacement

Question 14

Rank the intermolecular forced from strongest to weakest

Answer 14

Dipole ion– hydrogen bonding– dipole dipole— dispersion forces.

Question 15

For aA + bB — cC + dD… what is the rate

Answer 15

K(A)^x * (b)^y

X and y must be determined experimentally. They are the reaction rates

Question 16

Classic example of first order reaction

Answer 16

Process of radioactive decay

Question 17

Enthalpy change

Answer 17

The difference between the potential energy of the products and the potential energy of the reactants
