The third shell contanis one s orbital,three p orbitals and five d orbitals.Each orbital hold 2 electron so the total number of electron which can be accommodate in third shell are 18 electrons

4 0

Answer:

9

Explanation:

Hello,

In this case, since the third shell of electrons has  the following 3 subshells:

3s, 3p \ and \  3d

- The s subsehll has one orbital for one pair of electrons: s^1 \ and \   s^2.

- The p subsehll has three orbitals for three pairs of electrons: p^1, \ p^2,\ p^3, \ p^4,\ p^5\ and \ p^6\.

- The d subsehll has five orbital for five pairs of electrons d^1, \ d^2,\ d^3, \ d^4,\ d^5,\ d^6,\ d^7,\ d^8,\   d^9\ and \ d^{10}\.

Therefore, the total number of orbitals when n=3 is:

1+3+5=9

Best regards.

A location along stream where most erosions occur
vagabundo [1.1K]

Answer:

At a stream's headwaters, often high in the mountains, gradients are steep. The stream moves fast and does lots of work eroding the stream bed.As a stream moves into lower areas, the gradient is not as steep. Now the stream does more work eroding the edges of its banks.

hope that helps bby<3
