Answer:
elements in the same periodic table group have the same valence electrons
No that is false
Because its a organism. Which means at one point it was a live. It just died. You cant die if you were never alive. So that means that at one time was living.
But nonliving thing in science is like a piece of plastic cant breath eat die non living

Answer:
NH₃
Explanation:
The compound that is covalent from the given choices is NH₃.
Covalent compounds are usually formed between two atoms with similar values of electronegativities such that the difference is very small or zero.
- This bond type involves the sharing of electrons between two atoms with similar electronegativities.
- Nitrogen and hydrogen forms stable configuration that are isoelectronic with noble gases by sharing their valence electrons.
- The 3 hydrogen electrons are enough to make nitrogen isoelectronic with neon.
- Also, the nitrogen with 3 lone pairs of electrons provides the bonding hydrogen with needed electrons to attain a structure similar to helium.
Hope this helps
