Atom unit

Question 1

Five models of atoms

Answer 1

Dalton
Thomson
Rutherford
Bohrs
Schrodingers

Question 2

Dalton

Answer 2

All elements are made of atoms
Elements have whole number ratios

Question 3

Thomson

Answer 3

Atoms contain equal amounts of positive and negative charge

Question 4

Rutherford

Answer 4

Positive dense nucleus and negative electrons circling

Question 5

Bohrs

Answer 5

Electrons orbit the nucleus in specific levels of energy

Question 6

Schrodingers

Answer 6

Electrons are in probability zones and locations cannon be pinpointed
Atoms are particles and waves at the same time

Answer 9

2 down quarks and 1up quark

Question 10

Down quark

Answer 10

-1/3

Question 11

Up quark

Answer 11

2/3

Question 12

Gluons

Answer 12

The “glue” that holds quarks together

Question 13

Earliest designer of the periodic table

Answer 13

Dimitri Mendeleev

Question 14

Periodic

Answer 14

A regular repeating pattern

Question 15

Isotopes

Answer 15

Atoms with different numbers of neutrons

Question 16

Four ways to write an isotope

Answer 16

Nickel
Ni61
Ni-61
28-Ni-61

61
Ni
28

Question 17

Ions

Answer 17

Versions of an element that have lost or gained electrons on their valence shell

Question 18

Why do atoms become ions

Answer 18

So they can have a complete valence shell

Question 19

Cation

Answer 19

Positive ion
More protons

Question 20

What type of elements become cations

Answer 20

Metals on the left side of the table

Question 21

Anion

Answer 21

A negative ion
More electrons

Question 22

What type of elements become anions

Answer 22

Non-metals on the right of the periodic table

Question 23

Charge on ions that form group 1

Answer 23

+1

Question 24

Charge on group 2

Answer 24

+2

Question 25

Charge on group 13

Answer 25

+3

Question 26

Charge on group 15

Answer 26

-3

Question 27

Charge on group 16

Answer 27

-2

Question 28

Charge on group 17

Answer 28

-1

Question 29

Group 18

Answer 29

They already have a full valence shell (Nobel gases)

Question 30

Atomic radii trend

Answer 30

Atoms decrease in radius as it moves left to right across a period
Atoms decrease in radius as it moves up a group

Question 31

Ionization energy trend

Answer 31

Left to right across a period electrons are more difficult to remove
Bottom to top of a group electrons are more difficult to remove
