Concept explainers
Interpretation:
The particles that are present in equal numbers in neutral atoms has to be identified.
Concept Introduction:
An atom is considered to be simplest unit of any matter that makes up an element. It is further composed of 3 subatomic particles: electrons, protons, neutrons.
Negatively charged species are electrons, positively charged species are protons and neutral species are neutrons. Number of protons or electrons comprise
Answer to Problem 1PQ
Option (D) is the correct one.
Explanation of Solution
Reason for correct option:
Any neutral atom contains equal number of protons and electrons. Example, carbon atom, the electronic configuration is
Hence, correct option is (D).
Reason for incorrect option:
For electro-neutrality of species, electron and protons are equal in count as electrons possess unit negative charge and protons possess unit positive charge.
Therefore option (A), (B) and (C) are incorrect.
In all neutral atoms, equal number of protons and electrons are present. So the correct option is (D).
