Answer: Option (c) is the correct answer.

Explanation:

A change that does not bring any difference in chemical composition of a substance are known as physical properties.

For example, shape, size, mass, volume, density, etc of a substance are all physical change.

And, a change in which there occurs a difference in chemical composition of a substance then it is known as chemical change.

For example, precipitation, reactivity, toxicity etc are chemical change.

Fireworks exploding is a chemical change.

Thus, we can conclude that out of the given options fireworks exploding represents a chemical change.

Give the group number and general electron configuration of an element with each electron-dot symbol:
MatroZZZ [7]

The group number of (a) is VA(15) and electronic configuration is 1s2 2s2 2p3 . the group number of (b) is IVA(14) and the electronic configuration is 1s2 2s2 2p2 .

What is electronic configuration ?

it shows the distribution of electrons in the atomic orbitals .  

it follows a standard notation of s, p, d, f atomic orbitals in which electronic distribution of an atom occurs .

it has standard notation method as well as condensed electron configuration .

it is useful in determining the valency of an element .

it is useful in predicting the properties of a group of elements .

<h3>What is condensed electron configuration ?</h3>

It contains the symbol of the nearest , smaller noble gas in the square brackets and then the symbols of the occupied orbitals which contains valance electrons .

Example of condensed electron configuration is given by ,

in case of iron the electronic configuration is 1s2 2s2 2p6 3s2 4s2 3d6 .

Thus , the condensed electron configuration of iron is [Ar] 3d6 4s2 .
