Write the complete (long form) electron configuration AND include how many valence electrons there are for each of the following: a) Ga

b) Ir

Thanks!

Ga - 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p¹

Ir - 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²5d⁷

General Formulas and Concepts:

Chemistry - Atomic Structure

Explanation:

Step 1: Define

Ga - Element 31

Ir - Element 77

Step 2: Identify

Ga has 31 protons and 31 electrons. It is in Period 4 and in Group 13.

Ir has 77 protons and 77 electrons. It is in Period 6 and in Group 9.

Step 3: Electron Configurations

Ga - 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p¹

Ir - 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p⁶5s²4d¹⁰5p⁶6s²5d⁷

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
