Question

Calculate the atomic mass of natrium?​

Answer 1

Answer:

The Latin name of sodium is natrium. The atomic mass of sodium is 23 amu.

Explanation:

No.of protons in a sodium atom=11

No. of neutrons in a sodium atom=12

mass number= number of protons+ number of neutrons

=11+12

=23

Answer 2

Question :

Calculate Atomic Mass of Sodium.

Answer:

Atomic mass is the sum of number of protons and of neutrons.

Sodium contains eleven protons and twelve neutrons in it.

So, it's atomic mass is 23 u.

i.e.

Atomic Mass of Nitrogen = Number of protons + Number of neutrons

=> 11 + 12

=> 23 u

$\textbf{23 u is the Atomic Mass of}$

$\textbf{Sodium.}$
