Question

Identify the symbol for the element that contains 28 electrons in each of its neutral
atoms?
A. V
B. Ni
C. N
D. S
E. Si

Answer 1

Hint:Number of protons = number of electrons = atomic number of elements.When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is, therefore, zero and the atom is said to be neutral.

Complete step by step answer:
Vanadium(V) is a chemical element with atomic number23.
Silicon (Si) is a chemical element with atomic number 14.
Nickel is a chemical element with atomic number 28.
Nitrogen(N) is a chemical element with atomic number 7.
Sulphur(S) is a chemical element with atomic number 16.
Therefore, Nickel (Ni) has 28 protons and electrons in its neutral state and option (B) is correct.

Note:Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to provide a negative ion. The number of protons, electron present in the nucleus of a neutral atom is equal to the atomic number of a neutral element. The neutral state of an atom is typically the most stable configuration (unless molecular bonds and the chemical environment complicates the picture), so ions tend to discharge and return to their neutral state over time.
