Question

What does this symbol, 1/0N, mean?

A. an electron of negligible mass and one unit of charge
B. a position of negligible mass and one unit positive charge
C. a neutron of zero mass and one unit positive charge
D. a neutron of zero charge and one unit of mass

Answer 1

An element can be represented symbolically in terms of its atomic number and mass number as:

\[_{Z}^{A}\textrm{X}\]

where X = symbol of the element

A = atomic mass

Z = atomic number

In this case we have the representation as:

\[_{0}^{1}\textrm{n}\]

where n = symbol for neutron

mass number of neutron = 1

charge/atomic number of neutron = 0

Ans: D) A neutron of zero charge and one unit mass
