Question

Write a brief passage describing a neutral atom of

Answer 1

Answer:

There are 7 protons, 7 neutrons and 7 electrons in Nitrogen-14. Protons and neutrons are located in the nucleus, while electrons are located in electron shells. The number of protons determines the element's atomic number, the number of protons AND neutrons combined determine the element's mass number, and the average of the masses of all isotopes determines an element's atomic mass.

Explanation:

Hope this helps! :D

Answer 2

Answer:

Detail is given below.

Explanation:

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:

While 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

Location of electron, proton and neutron.

An atom consist of electron, protons and neutrons. Protons and neutrons are present with in nucleus while the electrons are present out side the nucleus.

All these three subatomic particles construct an atom. A neutral atom have equal number of proton and electron. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other. For example if neutral atom of nitrogen have 7 protons than it must have 7 electrons. The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom.

For example

Mass of nitrogen = number of neutron + number of proton

Mass of nitrogen = 7 + 7 = 14

Atomic number of nitrogen = number of electron or number of proton

Atomic number of nitrogen = 7
