Electrons and protons have opposite and equal charge and an atom has equal number of electrons as well as protons. Atoms are normally neutral. BookMyEssay tutors are experienced and trained in topics that range from basic Chemistry to Advanced Chemistry. Students avail our Atom research paper writing help to get grades top in their academics.
An Atom Structure
The structure of an atom is explained in our Atom essay homework writing help as follows:
- atomic nucleus
- nucleus part
The atomic nucleus is an atom’s center and it comprises of positively charged protons and neutrons that are uncharged. The additional nucleus part has a larger region that comprises of negatively charges particles known as electrons. An electron revolves around the center or the orbit of a nucleus. An atom is held together by an attraction between the electrons and the protons.
All atoms are made of subatomic particles; the only exception is hydrogen. Hydrogen contains one electron and one proton but does not have neutrons. The atomic nucleus is composed of fixed protons and they attract the same number of electrons thus making atoms electrically neutral. Ions are formed by removal or addition of electrons from atoms.

Atoms Make Compounds and Molecules
Atoms prefer company rather than being alone. Many atoms join with other atoms as they are more stable. Hydrogen atoms do not survive on their own rather they pair up and make a hydrogen molecule. Molecules are the smallest amount of compounds. A compound is a substance that is made from two or more than two atoms.
If two different elements join together, they make a new substance. One atom of oxygen and two atoms of hydrogen make a water molecule. Water is a compound as well as a molecule because it is formed by atom combination. Every molecule is not simple and small like water. Plastics molecules are made of hundreds and thousands of atoms that are joined together through long chains known as polymers. Just ask us, “write my homework for me on Atom”, we do it with 100% accuracy.
Charge of an Atom
Every atom is labeled either with a “–“, “+”, or “0”. The symbols are a charge of a particle. The electron has a negative or a “–“ charge. Proton has a “+” charge. If an atom has neutral or “0” charge, it means it has an equal number of protons and electrons. Neutron is a third particle and it has a zero charge.
As explained by our Atom assignment providers, the number of protons that are present in an atom does not alter, extra or fewer electrons may create a special atom known as an ion. Anions consist of additional electrons and they make a negative charge. Cations have lesser number of electrons and they have a positive charge.
