Question 1

Mendeleev

Answer 1

Created the first periodic table

Question 2

Periodic Law

Answer 2

When elements were arranged in order of increasing atomic number they will have similar physical and chemical properties.

Question 3

Metals (in case you forgot)

Answer 3

Shiny, conductive, malleable, ductile and solid at room temp.

Question 4

Nonmetals

Answer 4

Mainly liquid or gas at room temp
Brittle when solid
Poor conductors

Question 13

Atomic Radius

Answer 13

The distance between the nuclei of two atoms of the same element when they are joined.

Question 14

Ions

Answer 14

Charged atoms

Question 15

Cation

Answer 15

Positively charged atoms (Usually metals)

Question 16

Anion

Answer 16

Negatively charged atoms (Usually non-metals)

Question 17

Ionization Energy

Answer 17

The energy required to remove an electron from an atom.

Question 18

Electronegativity

Answer 18

the ability of an atom to attract electrons when the atom is in a compound

Question 19

Ionization and Electronegativity patterns

Answer 19

Both increase when going up and to the right of the periodic table.
(I.e. Oxygen being more electronegative than Lithium)

Question 20

Atomic Radius Pattern

Answer 20

Increases as you go to the right an
