question 11 (1 point)
(02.03 mc)
the following orbital notation is for which element?
1s 2s 2p 3s
o a na
o b he
o c f
o d o

Explanation:

Question 10

Count the total number of electrons in the orbital - notation. The 1s orbital has 2 electrons, the 2s orbital has 2 electrons, and the 2p orbitals have 5 electrons. The atomic number is equal to the number of electrons in a neutral atom. Nitrogen (N) has an atomic number of 7.

Count the electrons in each orbital. 1s has 2 electrons, 2s has 2 electrons, 2p has 6 electrons and 3s has 1 electron. The total number of electrons is 11. Sodium (Na) has an atomic number of 11.

Answer:

b. N
