Answer from: ssalazc1593

Magnesium. (B.)

Period is the horizontal row in the periodic table

Answer from: aupein

The answer is B

Explanation:

Elements in the periodic table are arranged according to there atomic numbers in groups (vertical columns) and periods (horizontal rows). Elements having the same number of valence electrons are in the same group in the periodic table while elements in the same period have the same number of electron shells.

Phosphorus has 3 electron shells, hence the right element in the options provided must have 3 electron shells in order to be in the same period with phosphorus.

Carbon has 2 electron shells hence it is found in period 2Magnesium has 3 electron shells hence it is found in period 3Nitrogen has 2 electron shells hence it is found in period 2Oxygen has 2 electron shells hence it is found in period 2

From the above, we can deduce that magnesium is found in the same period (period 3) with phosphorus.

Answer from: Quest

For cyclohexane compounds drawn in a chair conformation: -axial bonds are vertical -equatorial bonds are parallel to two bonds within the ring. thus, as i assume the chair conformation is drawn: -the x group is in an axial position, as are the five other vertical bonds. -three axial bonds are on the top face of the ring -the other three axial bonds are on the bottom face the position of the second substituent on each ring carbon is equatorial. gauche groups must be on an adjacent carbon such as carbon 6 and carbon 2, and also gauche groups are rotated by 60 degrees relative to each other. drawing the newman projections for c1–c2 and c1–c6 aids in visualizing the groups that are gauche to the y group on c1. click this link and watch some academic videos that may you more understand the topic
