Because atoms are made up solely Protons, Neutrons, and Electrons. Electrons have essentially no mass, so the other two are the only particles that fractor in.

How are neutrons and protons different?

Protons are positively charged and neutrons are neutral.


What best describes the mass of protons neutrons and electrons?

Protons and neutrons, which reside in the nucleus of an atom, have roughly the same mass, approximately 1 atomic mass unit (amu) each. Electrons, on the other hand, have a significantly smaller mass, about 1/1836 of a proton's mass, making them negligible in terms of overall atomic mass. Consequently, when calculating an atom's mass, the contributions from protons and neutrons are primarily considered, while electrons have a minimal effect.


Atom does not have to have equal numbers of protons and?

neutrons in order to be stable. The number of protons determines the element's identity, while the stability of the nucleus is influenced by the balance of protons and neutrons. Isotopes can have different numbers of neutrons while maintaining the same number of protons.


What kind of charge does the protons and neutrons have?

Protons are positively charged (+) and neutrons don't hold any charge.


Where are the protons and neutrons found in an atom?

Protons and neutrons are normally found in the atomic nucleus.


Where are the subatomic particles protons and neutrons located?

Protons and neutrons are located in the nucleus of an atom. The protons have a positive charge, while neutrons have no charge (they are neutral). The nucleus, containing protons and neutrons, is at the center of an atom and is surrounded by electrons.


Are neutrons the only particle that makes up the nucleus?

No, protons also make up the nucleus along with neutrons. Protons have a positive charge while neutrons have no charge. The number of protons determines the element, while the number of neutrons can vary within isotopes of the same element.


The nucleus of an atom is constituted of?

The nucleus of an atom is composed of protons and neutrons, which are held together by the strong nuclear force. The protons carry a positive charge, while neutrons have no charge. Electrons orbit around the nucleus in specific energy levels.


The nucleus of an atom contains the?

The nucleus of an atom contains protons and neutrons. Protons have a positive charge, while neutrons have no charge. The nucleus is the central core of an atom where most of its mass is concentrated.
