<em>Answer:</em>
- The atom have a full valence electron shell.
<em>Explanation:</em>
- My question is that why covalent bonds take place?
Every atoms tends to from bond with another atoms in order to get nearest electronic configuration of nobel gases. They become stable when their valence shell become complete. So when covelant bond forms between atoms, share electrons to each other and stabilize themselves.
Answer:
The number before any molecular formula applies to the entire formula. So here you have five molecules of water with two hydrogen atoms and one oxygen atom per molecule. Thus you have ten hydrogen atoms and five oxygen atoms in total.
Answer:
The correct answer is - option D. N2 + 3H2 → 2NH3.
Explanation:
N₂ + 3H₂ →2 NH₃
would be the correct equation as both hydrogen and nitrogen gas present in diatomic form thus the reactant would be N2 and H2. The charges of every atom of hydrogen and -3 and hydrogen hav one positive so the coefficent would be 3 for making bonds in the equation.
Answer:
B
Explanation:
Non metals do not conduct electricity
