Question

Atoms of the element beryllium would most likely behave similar to the way _______ behaves.

A. hydrogen
B. calcium
C. lithium
D. boron

Please explain why! Thanks :)

Answer 1

it's b. calcium
because the outer electron structure in all of that element is similar, they have the same chemical and physical properties.

Answer 2

Answer: The correct answer is Option B.

Step-by-step explanation:

Beryllium is the 4th element of the periodic table having electronic configuration
`1s^22s^2`. This element belongs to Group 2 of the periodic table.

Elements that belong to same group show similar chemical properties because they have same number of valence electrons.

For the given options:

Option A: Hydrogen

This element belong to group 1 of the periodic table.

Option B: Calcium

This element belong to group 2 of the periodic table. Thus, this will show similar chemical properties to beryllium.

Option C: Lithium

This element belong to group 1 of the periodic table.

Option D: Boron

This element belong to group 13 of the periodic table.

Hence, the correct answer is Option B.
