Question

directions: label the diagram below and place the charge next to each in the parenthesis. directions: answer the questions below by referencing a periodic table. 1. what atom is pictured above? 2. what is the atomic number for this atom? 3. what group is this element in? 4. what period is this element in? 5. is this element a metal, if so what type?

Explanation:

Step1: Identify atom by proton number

The number of protons determines the element. Here there are 4 protons, so the element is beryllium (Be).

Step2: Determine atomic number

Atomic number = number of protons. Since there are 4 protons, the atomic number is 4.

Step3: Find group on periodic table

Beryllium is in group 2 of the periodic table.

Step4: Find period on periodic table

Beryllium is in period 2 of the periodic table.

Step5: Classify as metal or not

Beryllium is an alkaline - earth metal.

Answer:

1. Beryllium (Be)
2. 4
3. Group 2
4. Period 2
5. Yes, alkaline - earth metal
