The red arrow is pointed at different locations of an atom of nitrogen. Where is it pointing to the greatest concentration of at
Mariulka [41]

Answer:

option A = In first diagram red arrow pointed towards the greatest concentration of atomic mass.

Explanation:

Every atom consist of nucleus or a positive center. The protons and neutrons are present with in the nucleus while electrons are present out side the nucleus. All these three subatomic particles construct an atom. The number of protons or number of electrons are the atomic number of an atom while the number of protons and number of neutrons are the mass number of an atom. A neutral atom have equal number of protons and electrons. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.

Nitrogen consist of seven protons and seven neutrons present with in nucleus and seven electrons are present out side the nucleus.

Electron:

The electron is subatomic particle that revolve around outside the nucleus and has negligible mass. It has a negative charge.

Symbol= e-

Mass= 9.10938356×10-31 Kg

It was discovered by j. j. Thomson in 1897 during the study of cathode ray properties.

Neutron and proton:

The neutron and proton are present inside the nucleus. Proton has positive charge while neutron is electrically neutral. Proton is discovered by Rutherford while neutron is discovered by James Chadwick in 1932.

Symbol of proton= P+  

Symbol of neutron= n0  

Mass of proton=1.672623×10-27 Kg

Mass of neutron=1.674929×10-27 Kg

Try moving an electron from the metal to the nonmetal. What happens?
skad [1K]

Answer:

Explanation:

When electron is transfer from metal to non metal anion and cations are formed and compound formed is called ionic compound.

Ionic bond:

It is the bond which is formed by the transfer of electron from metal to the atom of non metal.

Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity thus the atom which accept the electron is form anion and metal atom which lose the electron is form cation .

For example:

Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion the compound form is called sodium chloride.
