7 0

Answer:

B) 2

Explanation:

There are two significant figures in given measurement,

2, 0

Significant figures:

1= The given measurement have four significant figures 1534.

2= All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.

3= Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.

4= Zero between the non zero digits are consider significant like 107 consist of three significant figures.

5= The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.

The electron configuration of an element is 1s22s22p63s1.
k0ka [10]

The element is Sodium with an atomic number of 11 and electrovalent bonding takes place when it comes near an atom having seven valence electrons.

<h3>What is Electrovalent bonding?</h3>

This is also referred to as ionic bonding and involves the transfer of atoms of an element to another.

In order for both of them to achieve a stable octet configuration, sodium donates one atom to the element seven valence electrons.

Answer:

Heat of fusion

Explanation:

The heat required to change 1 gram of a solid at its normal melting point to a liquid at the same temperature is called the heat of fusion.

The formula for the heat of fusion is given by :

\Delta H=n\Delta H_{fus}

Where

n is no of moles

\Delta H_{fus} is molar heat of the substance

Hence, the correct answer is heat of fusion
