What activities do the nucleus do?

Answer 1

To understand the nucleus one must look to four forces that govern the interaction of all matter from galaxies to subatomic particles. These forces are contact free forces that cause both attraction and repulsion. They are ranked from strongest to weakest below.

1. Strong Nuclear Force

2. Weak Nuclear Force

3. Electromagnetic Force

4. Gravitational Force

For our purposes the nucleus is held together by strong nuclear forces. Over 1000 times stronger than electromagnetic forces, strong nuclear forces hold protons, neutrons, and the quarks (even smaller particles) that compose them together. Weak nuclear forces result in the loss of neutrons and therefore the ability of the human race to harness nuclear energy.

The nucleus would be boring if it held to itself only so the electromagnetic forces of the positive protons serve to attract electrons. Thus each nucleus is surrounded by a cloud of electrons. It is this cloud of the electrons and the attractions of all electrons to the positive nucleus of the atom that results in what we collectivelly call chemistry. Every cloud has a given number of shells (there are 4 kinds) and each shell has a certain number of electrons that can fill it based on the energy level of electron and the number protons in the nucleaus. The maximum number in an outer shell is generally 8. For example, oxegen has 8 protons and 8 electrons. Because the first shell in the cloud takes up two electrons there are 2 spaces availble for diffrent electrons. Hydrogen has 1 electron and 1 proton with its outer shell wanting 1 more. Because of the conservation of energy these atoms want to fill their outer shells. Therefore two hydrogen atoms and one oxegen choose to share electrons. The result is water.

This is called a covalent bond. Non-shared bonding is typically ionic, while collective sharing where electrons jump from atom to atom is called metalic bonding. While there are many other intracacies you can observe from the above that we should be very greatful that God gave us the nuclues.

Answer 2

have dna and rna and have chromosomes made up of dna which are the genetic information and it controls the functions in a cell also it control the type of enzymes
