<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

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:

<u>Option A:</u> Hydrogen

This element belong to group 1 of the periodic table.

<u>Option B:</u> Calcium

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

<u>Option C:</u> Lithium

This element belong to group 1 of the periodic table.

<u>Option D:</u> Boron

This element belong to group 13 of the periodic table.

Hence, the correct answer is Option B.

Three substances A, B, and C melt at 00C,500C and -1500C

Drupady [299]

Answer:

That information is better presented and analyzed in a table.

This table shows you all the information and the answers:

Substance         melting point   boiling point    room temperature    conclusion
                                    °C                  °C                      °C                (state)

A                                  0                    100                    25                    liquid

B                                  50                  200                    25                    solid
C                               -150                   10                 25                    gas

Explanation:

1) Substance A at 25° is above the melting point and below the boiling point, then it is liquid (just like water)

2) Substance B at 25°C is below the melting point, so it is solid.

3) Substance C at 25°C is above the boiling point, so it is gas.
