Which subatomic particles have the same relative mass?
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…
What is the mass and charge of each subatomic particle?
Introduction
| Particle | Electric Charge (C) | Mass (g) |
|---|---|---|
| Protons | +1.6022 x 10-19 | 1.6726 x 10-24 |
| Neutrons | 0 | 1.6740 x 10-24 |
| Electrons | -1.6022 x 10-19 | 9.1094 x 10-28 |
How do the masses of the three subatomic particles compare?
Both neutrons and protons are assigned as having masses of 1 amu each. In contrast, the electron has a negligible mass of . 0005 amu.
What are the 3 types of subatomic particles What are their charges and relative masses?
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.
How are the relative charge and relative mass of subatomic particles determined?
Since a nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus. Protons and electrons have opposite electrical charges….Subatomic particles.
| Subatomic particle | Relative mass | Relative charge |
|---|---|---|
| Proton | 1 | +1 |
| Neutron | 1 | 0 |
| Electron | 0.0005 | -1 |
Which subatomic particles have a mass?
Protons are positively charged particles, have mass, and are located in the center, or nucleus of the atom. Neutrons have no charge, have mass, and are also located in the nucleus of the atom.
What is relative charge?
So what we really mean is that if, say a quark has a charge of +2/3 we mean it is equivalent to (2/3 x 1.602 x 10^-9 Coulombs) Hence the number 2/3 is a number relative to 1 unit of proton charge. That’s all that is meant by “relative charge” .
Which option correctly describes the relative charges and masses of the subatomic particles?
Answer and Explanation: The correct statement is B. Protons and electrons have equal and opposite charges. Protons are positively-charged particles while electrons are…
What are the difference between the subatomic particles in terms of its relative charge?
Electrons surround the nucleus and have a negative charge and small mass relative to protons and neutrons Most of an atom’s mass Is In its nucleus, which is near the center and is composed of protons and neutrons Protons have a positive charge; neutrons have no charge.
When masses of subatomic particles are compared?
Subatomic particles
| Subatomic particle | Relative mass | Relative charge |
|---|---|---|
| Proton | 1 | +1 |
| Neutron | 1 | 0 |
| Electron | 0.0005 | -1 |
What is the comparison of subatomic particles?
Protons, Neutrons and Electrons Proton- A sub-atomic particle with a positive charge and a unit mass. Neutron- A sub-atomic particle with no charge and unit mass. Electron- A sub-atomic particle with a negative charge and negligible mass.
What is a relative charge of a particle?
Relative Atomic Charge is the charge of a particle compared to the charge of a single proton.
Which of the following correctly lists the pair of subatomic particles that balance the charge of the atom?
protons and electrons
8th Grade Matter & Energy
| Question | Answer |
|---|---|
| Which pair of subatomic particles balance the charge of the atom? | protons and electrons |
| What is the mass of an atom with seven protons, seven neutrons, and eight electrons? | 14 |
| What property uniquely identifies every element? | number of protons |
How do you identify the relative mass relative charge and location of the three subatomic particles of an atom?
How do they compare in terms of charge and relative mass?
The relative mass of a proton is 1, and a particle with a relative mass smaller than 1 has less mass. The mass of electrons is very small compared to protons and neutrons….Subatomic particles.
| Subatomic particle | Relative mass | Relative charge |
|---|---|---|
| Electron | 0.0005 | -1 |
Which subatomic particles contribute the most to the mass of an atom?
The protons contribute far more to an atom’s mass: one proton weighs about 2000 times more than one electron and there are equal numbers of protons and electrons in any neutral atom. The electrons contribute far more to the atom’s size: the diameter of the atom is about 10000 times the nuclear diameter.
Which of the following lists the two subatomic particles that contribute the most to the mass of an atom *?
Explanation: The protons and neutrons make up the nucleus. They both have a relative atomic mass of 1 compared to the electron which has a mass of 0.0005. This means, despite the nucleus being the smallest part of the atom, as the electron shell makes up most of it, the nucleus actually provides most of the mass.
