Answer:
slower
Explanation:
NBS is used in place of Br2 during bromination because the use of Br2 tends to result in the formation of a large concentration of the addition product. This is because, the Br2 interacts with the double bond to yield only the dibromide (addition product).
The usefulness of NBS lies in the fact that it provides a lower concentration of Br2, and such that the rate addition is slower than the chain propagation steps. Only the monobromination product is observed
The low concentration of Br2 allows the free-radical reaction to out-compete the alkene addition reaction.

Particles are measured in atomic mass units, or AMU.
Answer:
You can see in the above illustration of the periodic table that N is in Period 4, Group 5A, and p-block. Before reaching N, you will pass through the atomic orbitals 1s, 2s, and 2p. The electron configuration of N3- is N3-: 1s22s22p6 .
Explanation:
Answer:
ALL ISOTOPES OF AN ELEMENT HAVE THE SAME NUMBER OF;
1. PROTON
2. ATOMIC NUMBER
Explanation:
Isotopes are atoms with the same atomic number but different mass numbers. Isotopes of an element has the same number of proton which dictates the atomic number of the atoms. The difference in mass number is as a result of the difference in the number of neutrons. Isotopes of an atom have different physical properties but they exhibits the same chemical properties because neutrons have no influence on the chemical properties and the change or difference in neutrons will produce no effect on the chemical properties of the atoms. Neutrons only contributes to the mass of the atoms giving the isotopes of an atom different mass numbers. An example is chlorine with two isotopes, Cl -35 and Cl -37.
Properties Cl-35 Cl-37
mass number 35 37
atomic number 17 17
number of protons 17 17
number of electrons 17 17
number of neutrons 35-17 = 18 37-17 = 20
abundance in nature 75% 25%
