How do you describe subatomic particles?

A subatomic particle is a unit of matter or energy that’s the fundamental makeup of all matter. According to modern atomic theory, an atom has a nucleus, which is its center, or core. The nucleus contains subatomic particles: protons and neutrons. Electrons are negatively-charged particles.

Which subatomic particles identify atoms?

protons
Explanation: The identity of the element is determined by the number of protons, which are positively charged, massive nuclear particles. The number of protons in a nucleus is given by Z , the atomic number.

How do you describe the particles of an atom?

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

What are the sub atomic particles that make up an atom?

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below).

Which subatomic particle identifies an atom as that of a particular element?

Proton is the subatomic particle which identify the elements identity. Proton decides the atomic number of an element because atomic number = number of protons in the element. if the number of proton change, it changes the identity of element since each element has specific atomic number.

Where are subatomic particles located?

Subatomic particles include protons, neutrons and electrons. Protons and neutrons can be found inside the nucleus of an atom while electrons can be found around the nucleus floating in an electron cloud.

What are the masses of subatomic particles?

Masses for the three subatomic particles can be expressed in amu (atomic mass units) or grams. For simplicity, we will use the amu unit for the three subatomics. Both neutrons and protons are assigned as having masses of 1 amu each. In contrast, the electron has a negligible mass of .0005 amu.
