question 10 (1 point)\nwhich of the following is the correct noble gas notation for magnesium (mg)?\no a ne 3s²\no b ne 3s¹\no c he 3s¹\no d ar 2s²

Answer

Brief Explanations:

Magnesium has an atomic number of 12. Neon (Ne) is the noble - gas with an atomic number of 10. After filling the neon - like core, there are 2 remaining electrons which go into the 3s orbital. So the noble gas notation for magnesium is [Ne]3s².

Answer:

A. [Ne] 3s²
