Question 1

What are the physical properties of metals?

Answer 1

They are ductile, lusterous, malleable, very dense, good conductors of heat and electricity, very hard, magnetic, and have a high melting point

Question 2

What are the physical properties of nonmetals?

Answer 2

They are brittle, no luster (dull), poor conductors

Question 3

What is malleability?

Answer 3

The ability to be hammered into sheets or shapes

Question 4

What is the most reactive family of metals?

Answer 4

Question 5

What does atomic mass tell about an atom?

Answer 5

Number of protons and neutrons

Question 6

What do the groups/families in the periodic table have in common?

Answer 6

They have same number of valence electrons

Question 7

How many periods are in the periodic table?

Answer 7

Seven

Question 8

What do the periods on the periodic table have in common?

Answer 8

The same number of electron shells

Question 9

What are the names of the groups of the periodic table?

Answer 9

Alkali metals, alkaline earth metals, transition metals, borons, carbons, nitrogens, oxygens, halogens and noble gases

Question 10

What does an atomic number tell?

Answer 10

An atomic number tells the number of protons, which is the same as the number of electrons

Question 11

Where are nonmetals located on the periodic table?

Answer 11

To the upper right

Question 12

Where are metalloids located on the periodic table?

Answer 12

Along the zigzag line

Question 13

Describe the physical and chemical properties of the alkali metals

Answer 13

Soft, highly reactive, shiny, lusterous

Question 14

What happens to the charge on a metal atom when it loses an electron?

Answer 14

The charge becomes positive

Question 15

How many valence electrons are in each group of atoms?

Answer 15

Group 1: 1, Group 2: 2, Group 13: 3, Group 14: 4, Group 15: 5, Group 16: 6, Group 17: 7, Group 18: 8

Question 16

Mystery element: Has 3 electron orbits and 7 valence electrons. What is the name of this element?

Answer 16

Chlorine

Question 17

Mystery element: Has 4 electron orbits and 3 valence electrons. What is the name of this element?

Answer 17

Gallium

Question 18

What is the key strategy to determining the number of elements in a chemical compound?

Answer 18

Remember that each capital letter is a different element. (ex., CaCO(subscript)4 has 3)

Question 19

Determine the number of ATOMS in this molecule: CaCO(subscript)4

Answer 19

6 Atoms (Number after element shows 4 of the same element, 2 before, adding up to six)

Question 20

Be able to tell what atom an element will join with to make a STABLE compound!

Answer 20

Each element wants full valence, 8 in seconds, 2 in first, whichever applies.

Question 21

What is luster?

Answer 21

Shininess

Question 22

What is brittleness?

Answer 22

Shatters or breaks easily

Question 23

What is family based on?

Answer 23

Valence electrons

Question 24

What do lewis dot configurations show?

Answer 24

Valence electrons

Question 25

What is a radioactive atom or radioactivity?

Answer 25

An unstable atom decays to become stable. Consequently, it throws of energy during the process. It is the NEUTRONS that decay.

Question 26

What are valence electrons?

Answer 26

Outer shell electrons

Question 27

What is half-life?

Answer 27

The amount of time it takes for half of the radioactive atoms to decay and become stable.

Question 28

What were the three thing Marie Curie excelled at?

Answer 28

Patience, isolating variables, effort and perseverance. She discovered the two elements polonium and radium, and won the Nobel Prize in both chemistry and physics.
