What are 2 facts about subatomic particles?
Subatomic particles include electrons, the negatively charged, almost massless particles that nevertheless account for most of the size of the atom, and they include the heavier building blocks of the small but very dense nucleus of the atom, the positively charged protons and the electrically neutral neutrons.
What charge do each of the subatomic particles have?
There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have a charge.
Which subatomic particle has the most charge?
Proton

| Electron | e- | -1 |
What are the 3 charges of subatomic particles?
Proton (charge of +e, in the nucleus), Neutron (0 charge, in the nucleus), and Electron (charge of –e, outside the nucleus).
What subatomic particle has no charge?
In the middle of every atom is the nucleus. The nucleus contains two types of subatomic particles, protons and neutrons. The protons have a positive electrical charge and the neutrons have no electrical charge.
What charge does a neutron have?
no
neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67493 × 10−27 kg—marginally greater than that of the proton but nearly 1,839 times greater than that of the electron.
What subatomic particle identifies the atom?
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.
Which subatomic particle is the lightest?
electron
electron, lightest stable subatomic particle known. It carries a negative charge of 1.602176634 × 10−19 coulomb, which is considered the basic unit of electric charge. The rest mass of the electron is 9.1093837015 × 10−31 kg, which is only 1/1,836the mass of a proton.

What subatomic particle is negatively charged?
electrons
A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge. An atom usually contains an equal number of positively charged protons and negatively charged electrons.
Which is the heaviest particle?
Neutron
Neutron is heaviest subatomic particle among the given subatomic particles with mass of 1.008 amu while proton have mass of 1 amu.
What are sub atomic particles and their charges?
Alpha and Beta Particles. Alpha particles are made up of two protons and two neutrons and are emitted during the radioactive decay of unstable atoms.
What is subatomic particle always has a positive charge?
The proton is the subatomic particle with a positive charge. Neutrons are electrically neutral, while electrons are negatively charged. Read rest of the answer. Also asked, what is a possible charge on a particle? In physics, a charged particle is a particle with an electric charge.
What are negatively charged subatomic particles called?
Electrons – Negatively charged subatomic particles in an atom are known as electrons. An electron carries a charge of (1.602 times {10^{ – 19}}) Coulomb in magnitude. The mass of an electron is (frac{1}{{1837}}) times that of a proton. Protons – Positively charged subatomic particles in an atom are known as protons. The charge of a proton is equal to the charge of an electron in magnitude; but the charge is positive.
Are there particles smaller than sub-atomic?
One of the elements that make up a substance is an atom. Even smaller than this atom, the smallest unit of matter is said to be a subatomic particle in current research. However, there is an even smaller element than that subatomic particle, which is called a “Reishi”.
