What are atoms? What particles are they composed of? What is relative location and charge of each particle?

Atoms- An atom is the smallest unit of ordinary matter that forms a chemical element.
atoms are composed of protons, neutrons, and electrons.
the relative location of proton is inside the nucleus.
the relative location of neutron is inside the nucleus
the relative location of electron is outside the nucleus

Explanation:

an atom is the smallest chemical particle that exists

the are composed of 3 main things

protons

neutrons

electrons

protons and neutrons are located in the nucleus of the atomic structure( centre) and electrons are in shells out of the nucleus

protons are positive charged

electrons are negative charged

neutrons don't have a charge as their charge is too small and considered as nothing so 0

A recessive trait is often depicted as a lowercase letter, while a dominant trait is depicted as a capital letter. So, aa has two recessive genes, AA has two dominant genes, and Aa has both a dominant and a recessive gene. To eliminate the recessive gene, it has to have less of a chance of survival than the dominant gene. After a lot of time, if the aa or Aa gene keeps mixing with either AA or Aa genes, eventually the recessive gene will go away, although it will take many generations.
