Answer:garden steps that get closer together the further they are from teh ground
Explanation:
Quantized energy levels are discrete and get closer together the further they are from the nucleus
Answer:
ionic or covalent
Explanation:
The outermost electrons -- the valence electrons -- are able to interact with other atoms, and, depending on how those electrons interact with other the atoms, either an ionic or covalent bond is formed, and the atoms fuse together to form a molecule.
Answer:
A liquid's vapor pressure is directly related to the intermolecular forces present between its molecules. The stronger these forces, the lower the rate of evaporation and the lower the vapor pressure.
Explanation:
Answer:
C
Explanation:
C. Nucleophilic attack and carbocation rearrangement to form the most stable carbocation before the substitution reaction
Valence electrons in NH2Cl:
=1(5)*2(1)*1(7)
=14
So there are 14 valence electrons in NH2Cl
As each stick represents an valence electron pair.
And there are 14 valence electrons, so there can be 7 valence electron pairs.
And for 7 valence electron pairs, 7 sticks needed.
