Question

The symbol used for oxygen is ‘O’. There are 8 protons and 8 neutrons in its nucleus. From this determine the atomic number (Z) and mass number (A) of oxygen and arrange these in a conventional symbol.

Answer 1

Answer:

the atomic mass of oxygen is 16. it's atomic number is 8.

Explanation:

no.of protons = no.of electrons=atomic no.(Z)

the mass of an atom is concernetrated at its nucleus so the total no.of protons and neutrons is it's atomic mass.

Answer 2

Dear Student,

◆ Basic information -

• Atomic number of an element is the number of protons or electrons in the atom. It is denoted by letter Z.
• Total number of protons and neutrons in the nucleus is called atomic mass number. It is represented by letter A.

● Answer -

Oxygen symbol = ¹⁶O₈

● Explaination -

Atomic number is number of protons.

Z = p

Z = 8

Atomic mass number is no of protons and neutrons.

A = p + n

A = 8 + 8

A = 16

Symbol of an element is given by ᴬXz.

Hence, symbol for oxygen will be ¹⁶O₈.

Thank dear. Hope this helps you...
