Answer 6

5

Question 7

What types of atomic orbitals are in the htird principal energy level

Answer 7

S, P, and D only

Question 8

Emission of light from an atom occurs when the electon…

Answer 8

Drops from a higher to a lower energy level

Question 9

Each period number in the periodic table corresponds to…

Answer 9

A principal energy level

Question 10

What criterion is used to arrange the elements i rows and columns on the periodic table

Answer 10

SImilarity in properties

Question 11

The periodic law states that there is a periodic repetition of the physical and chemical properties of elements

Answer 11

When they are arranged in order of increasing atomic number

Question 12

Why is the radius of a positive ion always less than the radius of its neutral atom

Answer 12

The nucleus pulls the remaining electrons closer

Question 13

Why is the radius of a negative ion always greater than the radius of its neutral atom

Answer 13

Because the repulsion of electrons increases

Question 14

What term is used to describe an atom’s tendency to attract electrons to itself when it is chemically combined with another element

Answer 14

Electronegativity

Question 15

When do cations form

Answer 15

When an atom loses electrons

Question 16

What kind of ion does sulfur become when it combines with a metal

Answer 16

Anion

Question 17

What is the electrical charge of a cation

Answer 17

Positive

Question 18

What does the octect rule say

Answer 18

Eight electrons in their principal energy level

Question 19

What is the name given to the energy required to break a covalent single bond

Answer 19

Bond energy

Question 20

How many valence electrons does an atom of halogen have

Answer 20

7

Question 21

According to VSEPR theory, molecules adjust their shapes to keep which of the following as far apart as possible

Answer 21

Pairs of valence electrons

Question 22

What are the components of binary molecular compounds

Answer 22

Two metallic elements

Question 23

What is not true about all chemical reactions

Answer 23

New atoms are formed as products

Question 24

What is a driving force in a dr reaction

Answer 24

A precipitate is formed

Question 25

What is a false statement about yield

Answer 25

TAhe actual yeild may be different from the theoretical yeild because insufficent limiting reactant was used

Question 26

Bohrs model

Answer 26

- Energy levels - Electrons moves between energy levels when they gain and lose energy - Electrons emit light when they release energy and fall closer to the nucleus

Question 27

Bohr's model how do electrons emit light

Answer 27

- When energy comes in, the electron absorbs some enery and jumps away from the nucleus - The electron gives off that energy in the form of the light as the electron moves back towards the nucleus

Question 28

Why is silver always a plus 1 charge

Answer 28

5s^2 4d^9 One electon from s orbital moves to d so completely fille d and half filled s. It then loses the single electron from the s orbital

Question 29

Ionization energy

Answer 29

Amount of energy required to remove and electron

Question 30

Electron Affinity

Answer 30

Amount of energy released when an atom gains an electron

Question 31

Electronegativity

Answer 31

Amount of attraction an atom has for a bonded electron

Question 32

Lattice energy

Answer 32

AMount of energy reuiqred to separate a mole of ions in an ionic compound

Question 33

WHat are the types of IMF energies from weak to strong

Answer 33

LDF->DD->HB

Question 34

LDF

Answer 34

- A temporary dipole caused by a momentary unequal charge | - Made stronger by more electrons bc more electrons the higher probability for and unequal distribiution of charge

Question 35

DD

Answer 35

A permenant partial positive and partial negative charge (dipole) cuased by polar bonds an an asymmetrical molcule -The greater the EN dif, the greater the strength there is a larger difference in the sharing of electrons,, so a greater partial positive and negative charge

Question 36

HB

Answer 36

A very stong dipole caused by hydrogen being attached to nitrogen, flourine, or oxygen

Question 37

Spectator ion

Answer 37

Ions that don't participate in the formation of solid, liquid, or gas, so they get crossed out
