why atom is chargeless
Answers
if we take away or give it electrons it gains charge and is called an ion
Answer:
The number of protons (positively charged) and electrons (negatively charged) is equal in an atom. Therefore, the opposite charges are balanced and thus the atom has no net charge. Furthermore, neutrons in an atom have no charge. Thus, the atom is electrically neutral.
More about the atom:
An atom is the basic unit of matter that makes up a chemical element. Each atom consists of a nucleus and one or more electrons attached to the nucleus. A nucleus consists of one or more protons and many neutrons. Only the most common hydrogen has no neutrons. Every solid, gas, liquid and plasma is made up of neutral or ionized atoms. Atoms are extremely small, usually about 100 picometers in diameter. They are so small that it is impossible to accurately predict their behavior using classical physics, as if they were tennis balls, for example due to quantum effects.
Over 99.94% of the mass of an atom is located in the nucleus. Protons have a positive electrical charge, electrons have a negative electrical charge, and neutrons have no electrical charge. If the number of protons and electrons is equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, it has a negative or positive charge, respectively - such atoms are called ions.
