Atoms

Question 1

Protons

Answer 1

Positive, in Nucleus. =atomic #

Question 2

Neutrons

Answer 2

Neutral, in Nucleus (protons+ neutrons = atomic mass [below element letters])

Question 3

Electrons

Answer 3

outside of neutron, make up energy clous. Negative

Question 4

How do you determine how many of each particle there is in each atom?

Answer 4

compound, how many protons and neutrons

Question 5

Isotope

Answer 5

varies atomic mass. varying # of neutrons

Question 6

Ion

Answer 6

atom that has a charge. varying # of electrons. positive or negative. Electrons can vary, protons cannot.

Question 7

Where are metal, metalloids and non-mettals located?

Answer 7

Metals- first few groups (about 1-13
Non-metals- about 14-18
Metalloids- about 13-17

Question 8

alkali metals?

Answer 8

group 1, very reactive

Question 9

Earth metals?

Answer 9

group 2, reactive

Question 10

Noble Gasses?

Answer 10

group 18, not reactive. outside ring is full.

Question 11

halogens?

Answer 11

group 17, reactive

Question 12

How many of each atom is found in compounds? Determine how many protons and electrons make what charge?

Answer 12

MATTHHHH!!!!
Compounds: like exponents
Protons= positive #s, Electrons= negative #s ad them!!!! 4 protons+ 5 electrons = -1 charge

Question 13

Transition elements

Answer 13

groups 3-16

Question 14

Period

Answer 14

go left to right, go by atomic number

Question 15

Group

Answer 15

go down, similar properties

Question 16

Element

Answer 16

all the same atom

Question 17

Compound

Answer 17

molecule, linked atoms

Question 18

Mixture

Answer 18

combination of two substances that can be separated “sand and water”

Question 19

Properties of metals?

Answer 19

Shiny, shape easily, conduct electricity, solid at room temperature (except for mercury)

Question 20

Non-metals?

Answer 20

halogens react, noble gasses not reactive, dull, brittle, gasses or liquids

Question 21

Physical properties

Answer 21

density, how they look/feel

Question 22

chemical properties

Answer 22

what it is made from, compound, elements, what it reacts to if reactive
