Question 4

Name the first 5:

Answer 4

Hydrogen - H, Helium - He, Lithium - Li, Beryllium - Be, Boron - B

Question 5

How is the periodic table organized?

Answer 5

The elements are organized in horizontal rows (or periods) by order (atomic number increases each time).

Question 6

Name the different groups in the periodic table:

Answer 6

Alkali metals, alkali earth metals, metal, metaloids, non metals, halogens, and noble gases. (Lanthanides & actinides)

Question 7

What is a period?

Answer 7

Each numbered row is a period.

Question 8

Define groups in the periodic table:

Answer 8

Each column of elements (ex: alkali dart metals, non metals, metals, metaloids, noble gases, alkali metals, halogens)

Question 9

What are the group properties?

Answer 9

1. The group number is the number assigned to the vertical column of elements. 2. Elements within the same group have the same number of electrons in their outer shells. 3. All elements in the group have similar chemical properties.

Question 10

Why are noble gases (inert) special?

Answer 10

(They are in group 18 on the periodic table) They are stable because they have he maximum number of valence electrons that their outer shell can hold. (They rarely react with other elements because hey are stable).

Question 11

Why does Ne not form an ion or a compound?

Answer 11

Neon has a full outer shell, therefore no borrowing or loss of electrons is needed because the noble gas is already stable and cannot form a compound ion because it is “inert”.

Question 12

Subatomic particles that make up an atom:

Answer 12

Protons (located in the nucleus), neutrons (also located in the nucleus), and electrons (they orbit the nucleus)
