Hint: The answer to this question is based on the basic concept of chemistry which has the formula to calculate the charge on the protons which is given by $\text{Charge}={{n}_{p}}-{{n}_{e}}$ and this lead to correct answer.
Complete step by step solution:
In the lower classes of chemistry we have studied about the structure of atoms and its constituents and also the way to calculate the electronic configuration.
- Now, let us know what is an atom and its constituents which makes you lead you to the exact answers.
- An atom is basically defined as the smallest part of the chemical element that exists which makes an element. Atoms are extremely small to about 100 pico meters across.
- We have studied in the previous classes that an atom is made up of three basic particles namely: protons, neutrons and the electrons.
- Protons and the neutrons are concentrated at the centre of nucleus of an atom and electrons are revolving around the nucleus of an atom in an orbit and this region is called an electron shell.
- Also, the number of protons (Z) and electrons in an atom are always equal and the mass number of the atom is given by the sum of protons and neutrons.
- To calculate total charge on the species the formula is given y,
Charge on the species = number of protons – number of electrons
That is,
$\text{Charge}={{n}_{p}}-{{n}_{e}}$
Thus substituting the values from the given data we have,
Charge = 17- 18 = -1
Therefore, the correct answer is option B)
Note: Chances of confusion between the formal charge and the electric charge may occur but note that formal charge is the name used to estimate the way in which the electric charge is distributed in a molecule.
