Question

HELPPPP

Which lists the elements in order from most conductive to least conductive?


1. potassium, selenium, germanium

2. germanium, potassium, selenium

3. selenium, germanium, potassium

4. potassium, germanium, selenium

Answer 1

nitrogen (N), antimony (Sb), bismuth (Bi)

Explanation: just go back on the periodic table. i also got it right on edge.

Answer 2

Option 4: potassium, germanium, selenium

Step-by-step explanation:

A Selenium atom has 34 electrons and its ground state electron configuration is 1s2, 2s2, 2p6, 3s2, 3p6, 3d10, 4s2, 4p4

This means it has 6 electrons in it's outermost shell.

Germanium :

A Germanium atom has 32 electrons and its ground state electron configuration is 1s2, 2s2, 2p6, 3s2, 3p6, 3d10, 4s2, 4p2. This means it has 4 electrons in it's outermost shell.

Potassium:

A potassium atom has 19 electrons and its electron configuration is; 1s2, 2s2, 2p6, 3s2, 3p6, 4s1. This means it has 1 electron in it's outermost shell.

In reactivity, the element with the most number of electrons in it's outermost shell will be the least conductive.

Thus, the most conductive is potassium followed by Germanium then selenium
