Write the outer electron configuration for the group 15 element in the fourth period.

4s² 4p³

Explanation:

1) To determine the outer electron configuration of an element you need to know the number of electrons and use Aufbau rules (or the energy levels of of the electrons).

2) The number of electrons of a neutral atom is equal to the number of protons.

3) The number of protons is the atomic number of the element.

4) The elements are arranged in the periodic table in attendance of the atomic number.

5) The elements in the group 15 are N, P, As, Sb, Bi, and Mc.

6) N is in the second period, P is in the third period, and As is in the fourtn period. So, your element is As.

7) The atomic number, number of protons, and number of electrons of As is 33.

8) Now you can distribute the electrons according to Aufbau rules:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³

9) The outer shell is n = 4, so the outer electron configuration is 4s² 4p³

passed in september 1935, these laws are known as nuremberg laws.   they forbid jews from marrying but not directly forced them to divorce aryans. what is most noticeable is the fact that the jews were defranchised, meaning by this that they were not expected to have any civil rights, including the right to vote. the right answer is deprived of the right to vote.

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.
