Give the symbol for the atom that corresponds to each electron configuration:
1s22s22p63s1
1s22s22p3
1s22s22p63s23p2
1s22s22p4
1s22s22p63s23p64s1
1s22s22p63s23p63d24s2

any with be appreciated.

Na

N

Si

O

K

Ti

Explanation:

To know what symbol corresponds to the electron configurations, we just have to count the number of electrons.

⇒1s² 2s² 2p6 3s1

This means there are 2 electrons on the first shell

8 electrons on the second shell

and 1 electron on the third shell

in total there are 11 electrons ⇒ this means the atom number is 11

If we look at the periodic table to atom number 11 we'll see that this is Sodium (Na).

⇒ 1s² 2s² 2p³

This means there are 2 electrons on the first shell

and 5 electrons on the second shell

So 7 electrons in total ⇒ this means the atom has atom number 7

⇒Nitrogen (N)

⇒ 1s² 2s² 2p6 3s² 3p²

This means there are 2 electrons on the first shell

There are 8 electrons on the second shell

There are 4 electrons on the third shell

So there are 14 electrons in total ⇒ atom number 14

⇒Silicon (Si)

⇒1s² 2s² 2p4

This means there are 2 electrons on the first shell

There are 6 electrons on the second shell

8 electrons in total ⇒ atom number = 8

⇒Oxygen (O)

⇒ 1s² 2s² 2p6 3s² 3p6 4s1

This means there are 2 electrons on the first shell

There are 8 electrons on the second shell

There are 8 electrons on the third shell

There is 1 electron on the fourth shell

This means there are 19 electrons in total ⇒ atom number 19

⇒Potassium (K)

⇒ 1s² 2s² 2p6 3s² 3p6 3d² 4s²

This means that 2 electrons on the first shell

There are 8 electrons on the second shell

There are 10 electrons on the third shell

there are 2 electrons on the fourth shell

There are 22 electrons in total ⇒ atom number 22

⇒ Titanium (Ti)

b. is the answer hoped i        

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
