Question

P. T m shell contains 9orbirals and 18electrons​

Answer 1

Answer:

True

Explanation:

We know that, M is the 3rd shell

K=1st, L=2nd, M=3rd and so on

We know that number of orbitals in a particular shell is

${n}^{2}$

where n= no. of shell

here, n= 3 for M

Hence, number of orbitals is 9

We know that each orbital contains 2 electrons

so, the number of electrons= 2 × number of orbitals

no. of electrons=2×9

no. of electrons=18

Hence proved

Answer 2

Answer:

So in the orbit there will be :-

First orbit-2 electrons

Second orbit-maximum 8 electrons

Third orbit-8 electrons

Explanation:

As you know always there will be 2 electrons,In the second maximum should be 8 electrons and in the third there will be 8 electrons
