What else can I help you with?
Can you give me a sentence with the word electron?
The electron is a subatomic particle with negative elementary charge.
Which subatomic particle gives the nucleus its electric charge?
Protons are the subatomic particles that give the nucleus a positive electric charge. Electrons, with a negative charge, surround the nucleus.
Can a particle accelerator give you superpowers?
No, a particle accelerator cannot give you superpowers.
How do subatomic particles tells you what element it is?
Subatomic particles identify elements based on the number of protons in the nucleus. Protons give the element its identity, as each element has a unique number of protons. This number is known as the atomic number, and it determines how the element behaves chemically and physically.
What subatomic particle makes an element unique?
The number of protons is unique for every element.Varying the number of neutrons will give you an isotope of the same element.Varying the number of electrons will give you an ion of the same element.
What is the process in which an atomic nucleus expels a helium nucleus?
We give the name alpha decay to this nuclear decay event. The alpha particle, which is a pair of protons and a pair of neutrons bound together, is, in fact a helium-4 nucleus.
Protons and neutrons in the nucleus add up to give the?
The number of protons added to the number of neutrons in a nucleus give that isotope's atomic weight.
What does an alphaparticle give off?
An alpha particle is equivalent to a nucleus of the helium-4 atom.
Can you give me a sentence with the word electron?
The electron is a subatomic particle with negative elementary charge.
If you know the atomic number and the mass number of an isotope how could you figure out the number of neutrons in its nucleus.?
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
Which subatomic particle gives the nucleus its electric charge?
Protons are the subatomic particles that give the nucleus a positive electric charge. Electrons, with a negative charge, surround the nucleus.
Why does an alpha particle have a charge of 2 positive?
The alpha particle (which is a helium nucleus), is composed of two protons and two neutrons. The two protons give it a charge of +2.
If you know the atomic number and the mass number of an isotope how could you figure out the number of neutrons in its nucleus?
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
What information could you use to determine the atomic number of an unknown element that has the mass number of 22?
To determine the atomic number of an unknown element with a mass number of 22, you would need to know the number of protons in the nucleus of the element. Since the mass number is the sum of protons and neutrons, subtracting the number of neutrons from the mass number would give you the atomic number. This is because the atomic number represents the number of protons in an element's nucleus.
When a parent radioactive nucleus splits by ejecting an alpha particle the remaining nucleus has what left?
two protons and two neutrons less than the original nucleus.* A lower atomic mass (-4)* A lower atomic number (-2)In alpha decay, an alpha particle (helium nucleus) is given off.An alpha particle consists of 2 protons and 2 neutrons. THus the atom loses 2 protons and 2 neutrons. Proton number endows the identity of the element. The daughter nucleus is thus of a different element to the parent nucleus. It also has 2 fewer protons. Radium can decay by alpha emission, losing 2 protons from the original 88, leaving a nucleus of Radon with 86 protons.Neutrons and protons summed give the mass number of the atom. SInce an alpha-decayed nucleus loses a sum of 4 particles (protons and neutrons) the mass number goes down by 4.NovaNET answer: 2 protons and 2 neutrons less
Any element can always be identified by its?
The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
What is the Positivly charged particle in the nucleus of atoms?
A particle with a positive charge in the nucleus of an atom is called a proton. Protons and neutrons make up the nucleus. Neutrons have no charge. Electrons are tiny electronegative particles that orbit the nucleus.
