Question

An element has mass number 35 and number of neutron atom is 18. what will be the formula of chloride of element x?

Answer 1

Answer:

x is chlorine and there is no formation of chloride

Answer 2

Explanation:

Mass number of element is 35

Number of neutrons= 18

Formula to find number of protons:

Mass number = number of protons + number of neutrons.

35=× +18

×=35 - 18

X=17.

Number of protons =17 and number of electrons also will be 17 as atom is electrically neutral.

Hence Element is chlorine and chloride will not form of this element
