Use the periodic to fill in the numbers in the electron configurations shown below. Na: 1822sC2pP3sE C =
D =
E =

Values of the electron configuration of Na:

C=2

D=6

E=1

Given

The electron configuration of Na

Required

Fill the number in the electron configuration

Solution

Sodium with the symbol Na is an alkaline metal located in group 1 and has the atomic number 11.

Electron configuration is based on the number of electrons.

Because the atomic number of Na is 11, the number of protons = the number of electrons for the element Na is 11

So the electron configuration is:

1s² 2s²2p⁶3s¹

answer: h+ its less than oh

explanation:

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
