What Two Subatomic Particles Have The Same Mass

What two subatomic particles have the same mass?

Answer and Explanation: The two subatomic particles that have the same mass are protons and neutrons. Neutrons and protons each have an atomic mass of about one atomic mass unit (amu).

Which two subatomic particles have approximately the same mass quizlet?

Proton and electrons are two subatomic particles that have approximately the same mass. Electrons are attracted to the positive of an electric field. Isotopes of an element differ only in the number of protons. The volume occupied by the nucleus of an atom represents a large percentage of the total volume of the atom.

Which of the pair of subatomic particles have equal mass?

The mass of a proton is nearly same as the mass of a neutron, whereas the mass of an electron is nearly (11836)times that of the proton.

What 2 subatomic particles represent the mass?

Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons.

What subatomic particles are always the same?

Each atom of an element contains the same number of protons, which is the atomic number (Z). Neutral atoms have the same number of electrons and protons. Atoms of an element that contain different numbers of neutrons are called isotopes.

Is proton and electron have same mass?

They have different masses! The mass of an electron is 9.109 x 10^-31 kg. The mass of a proton is 1.672 x 10^-27 kg. The mass of a neutron is 1.674 x 10^-27 kg.

Which has the smallest mass?

Answer and Explanation: Here, the mass of an electron is the smallest as compared to all particles.

Which 2 subatomic particles have practically the same mass of 1 amu?

The mass of protons and neutrons are nearly the same that is, about. 67 × 10 – 24 grams, which scientists define as one amu or atomic mass unit or one Dalton.

Which subatomic particle has no mass?

The two particles physicists know to be (at least approximately) massless—photons and gluons—are both force-carrying particles, also known as gauge bosons. Photons are associated with the electromagnetic force, and gluons are associated with the strong force.

Which subatomic particle is the heaviest?

Neutron is heaviest subatomic particle among the given subatomic particles with mass of 1.008 amu while proton have mass of 1 amu.

Which subatomic particle is the smallest?

Quarks are among the smallest particles in the universe, and they carry only fractional electric charges.

Which particle has no charge?

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 two particles are equal in number?

Protons and electrons are present in equal numbers in neutral atoms.

What is the mass equal to 1 amu?

One amu = The aggregate of the proton and neutron rest masses. 1 amu is equal to 1.67377 x 10-24 grams or 1.67377 x 10-27 kilograms. 12 amu is the mass of one atom.

What subatomic particle has mass equal to or greater than a proton?

The remainder of the hydrogen atom’s mass comes from the positively charged proton. The atomic number of an element is the number of protons in its nucleus. Neutrons are neutral particles having a mass slightly greater than that of the proton.

Which pair has identical value of em?

An α-particle has 2 protons and 2 neutrons. Deuterium has one proton and one neutron. Hence, they have identical values of e/m. Was this answer helpful?
