Question

Boron has two stable isotopes ...The atomic that should appear for boron in periodic table

Answer 1

Explanation:

boron has 2 stable isotopes,10b(19%)and11b(81%) the atomic mass that should appear for boron in periodic table is.

Answer 2

Answer:

The isotopes are certain elements that have the similar atomic number but different atomic mass. This difference is mainly due to the difference in the number of neutrons; the number of 'protons' always being the same. Boron has 2 stable isotopes, 10b (19%) and 11b (81%)So, the 'atomic mass' of boron will be an average content of the two isotopes of Boron.

Atomic Mass will be = 10*9+ 81*11/100 => 1081/100

$\huge{\boxed{At.Mass = 10.81}}$
