Answer:
It's better to explain it.
Explanation:
Neutrons do not affect the electron configuration, but the sum of atomic number and the number of neutrons, or neutron number, is the mass of the nucleus. You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there. Neutron numbers are able to change the mass of atoms, because they weigh about as much as a proton and electron together. if your asking What is the role of a neutron in an atom? then, Neutrons are very important in providing stability for an atom. Some atoms don't "need" neutrons - The hydrogen atom does not have any neutrons. However, as the atomic number ( # of protons ) increases, the number of neutrons increases as well.
Protons don't like each other. Naturally, 'positive charges repel', so it wouldn't be possible to have more than one proton in the nucleus. Here's where the neutron comes in.
Hope this helps. :)
Answer:

Explanation:
Substance abuse is related to misuse of toxic or hazardous substances for example alcohol, and illicit drugs. It leads to the psychoactive substances responsible for substance syndrome.
It is active due to global impairment in cognition, behavioral, and physiological phenomena that are developed after the repeated use of the substances abuse that is related to the strong desire to use the drugs.
the answer is 0.0693769. 6.02x10^21 x6.94/ 6.022x10^23 is the formua you would use.
Answer: D. Amount of substance present in Avogadro‘s number of particles of the substance
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP, contains avogadro's number 
of particles and weighs equal to the molecular mass of that substance.
A mole is defined as the amount of substance that contains Avogardro number of the substance. Avogadro's number is given by 
.
particles
