A noble gas electron configuration follows the octet rule in which the configuration is composed of electrons. the charge of a neutral atom is zero. meanwhile, a magnesium atom bears a + 2 charge which means in order to be stable, it has to gain two electrons to be stable.
The ratio that show the relationship between moles of each reactant and product in the reaction that is
N2 + 3 H2 = 2NH3
the ratio is as follows
1mole N2 : 3 mol H2 :2mol NH3
This ratio is from equation since there is 1 mole of N2 reacted with 3 moles of H2 to produce 2 moles of NH3
4. it remains in its initial phase
Answer:
Ca:
Explanation:
A Lewis structure shows the number of valence electrons about an atom.
Ca is in Group 2 of Period 4.
Its electron configuration is [Ar]4s².
Thus, Ca has two valence electrons and its Lewis structure is Ca:
