Answer 1

because it follow nobel gas configuration

Answer 2

Hi dr, gud mrng....

A sample of boron contains the two isotopes, boron-10 and boron-11.

This is a simple algebra problem. You can state it with two variables:

x = percentage of B-11

y = percentage of B-10.

x + y = 1, of course.

but also, 11x + 10y = 10.8

HOPE THIS HELPS.....♥♥
