What makes calcium and nitrogen different list two differences

Chemistry
1 answer:
liberstina [14]3 years ago
6 0

Answer:

the difference in electronegativity is so large (2.04) that the bonding electrons spend almost all their time on the nitrogen atom.

Explanation:

Because calcium loses 2 electrons to become Ca2+, and nitrogen gains 3 electrons to become N3−, you need two calcium atoms and three nitrogen atoms in order to form a neutral compound.

DochEvi [55]

Explanation:

In periodic table:

  • Elements are arranged according to their atomic number in increasing order.
  • When we move left to right we move along a period.The period in the periodic table tell us about the principal quantum number,(n).
  • When move from top to bottom we are moving in group. The group in the periodic table tell us about the number of the valence electrons present in the valence shell of the elements of the particular group.

Answer:

C: The atoms involved in the chemical reaction

Explanation:

In a chemical reaction, when we balance it up, the number of moles or atoms on the left side must equal that on the right hand side. And thus, the mass is found in the atoms involved in such chemical reaction.
