Atom Models

Identify the element described in each question. You will need a periodic table to help you.

Each answer will have the element name (symbol) (atomic number) to help you find it on the periodic table

For example:

Lithium (Li) (3)

REMEMBER....

Total Protons or Electrons =

Atomic number

Multiple Choice

What element is it?

• Lithium (Li) (3)

• Hydrogen (H) (1)

• Beryllium (Be) (4)

Multiple Choice

What element is it?

• Lithium (Li) (3)

• Carbon (C) (6)

• Fluorine (F) (9)

Multiple Choice

An element has 11 protons, 11 electrons, 12 neutrons. What element is it?

• Copper (Cu) (29)

• Potassium (K) (19)

• Sodium (Na) (11)

Multiple Choice

An element has 7 protons, 7 electrons, 7 neutrons. What element is it?

• Helium (He) (2)

• Potassium (K) (19)

• Nitrogen (N) (7)

REMEMBER...

Periods =

Energy levels (Cloud circles)

Families (Groups) =

Valence electrons (The outermost electrons)

Multiple Select

Which elements have 3 energy levels? (Choose all that are correct.)

• Sodium (Na) (11)

• Magnesium (Mg) (12)

• Boron (B) (5)

• Chlorine (Cl) (17)

Multiple Select

Which elements have 1 energy level? (Choose all that are correct.)

• Sodium (Na) (11)

• Hydrogen (H) (1)

• Boron (B) (5)

• Helium (He) (2)

Multiple Select

Which elements have 4 energy level? (Choose all that are correct.)

• Sodium (Na) (11)

• Potassium (K) (19)

• Calcium (Ca) (20)

• Krypton (Kr) (36)

Multiple Select

Which elements have 2 valence electrons? (Choose all that are correct.)

• Beryllium (Be) (4)

• Magnesium (Mg) (12)

• Hydrogen (H) (1)

• Calcium (Ca) (20)

REMEMBER...

Drop the digit of 1 when looking for valence electrons in families 13-18

For example:

Family 13 = 3 valence electrons

Family 14 = 4 valence electrons

Family 18 = 8 valence electrons

Multiple Select

• Neon (Ne) (10)

• Magnesium (Mg) (12)

• Argon (Ar) (18)

• Krypton (Kr) (36)

Multiple Select

Which elements have 6 valence electrons? (Choose all that are correct.)

• Neon (Ne) (10)

• Oxygen (O) (8)

• Sulfur (S) (16)

• Boron (B) (5)

Multiple Choice

An element has 2 energy levels and 2 valence electrons. What element is it?

• Lithium (Li) (3)

• Beryllium (Be) (4)

• Helium (He) (2)

Multiple Choice

An element has 3 energy levels and 5 valence electrons. What element is it?

• Lithium (Li) (3)

• Nitrogen (N) (7)

• Phosphorus (P) (15)

CHALLENGE yourself!!!

Be sure to think about all you have learned and use a periodic table with family names included.
