Question

In an element’s square on the periodic table, the number with the greatest value represents the

A.number of neutrons.
B.number of electrons.
C.atomic number.
D.atomic mass.

Answer 1

Answer: D.atomic mass.

Step-by-step explanation: The general representation of an element is given by:
`_Z^A\textrm{X}`

X = chemical symbol of element

Z= atomic number= which represents the number of electrons.

A= mass number or atomic mass =which represents the number of electrons + number of neutrons

Thus mass number is greater than number of electrons and number of neutrons as it is the sum of both.
