Whwn an alpha particle is lost we lose 2units of +ve charges and 4 units of mass no.

So we are left with mass no.(M-4) and charge (C-2)

M=initial mass no.

C=initial charge

Here 1 unit of charge used is= 1*1.6*10^-19 coulomb

Which number in a nuclear chemical symbol represents the charge of the particle?

The number in a nuclear chemical symbol represents the charge of the particle is the atomic number or the number of protons in the nucleus.


When a beta particle is ejected from a nucleus the nucleus then has greater?

When a beta particle is ejected from a nucleus, the nucleus gains one unit of positive charge as it transforms a neutron into a proton. This results in an increase in the atomic number of the atom while the mass number remains the same.


What subatomic particle has a relative mass of 1?

The term nucleon is applied to any particle that makes up an atomic nucleus. That means it can be applied to either a proton or a neutron (but only when we are talking about them as the components of an atomic nucleus). The nucleon with the positive charge is the proton. You'll recall that the neutron is a neutral particle; it has no charge.


What is a protron?

A proton is a subatomic particle found in the nucleus of an atom. It has a positive electrical charge and is roughly 1,836 times more massive than an electron. The number of protons in an atom determines its atomic number and chemical properties.


What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?

When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.

What is a positively charged particle of the nucleus?

A positively charged particle in the nucleus is a proton. Protons have a positive electrical charge and are responsible for determining the atomic number of an atom.

When beta particle is ejected from a nucleus does it have a greater mass or charge?

The beta particle is formed when a neutron decays into a proton and electron. So the number of protons increases, causing an increase in the charge of the nucleus by 1, and a very tiny decrease in mass.

What is a unionized particle of an element?

A unionized particle of an element refers to an atom that has not gained or lost any electrons, thus maintaining a neutral charge. This means the number of protons in the nucleus is equal to the number of electrons orbiting the nucleus.


What happens to a radioactive nucleus when it emits alpha particle and What happens to a radioactive nucleus when it emits alpha particle?

When a radioactive nucleus emits an alpha particle, it decreases by two protons and two neutrons. This results in a new nucleus with a lower atomic number by 2 and lower mass number by 4. The emitted alpha particle is a helium nucleus (2 protons and 2 neutrons) and carries a positive charge.

Which particle determines the nuclear charge?

Protons determine the nuclear charge of an atom. Each proton carries a positive charge and is located in the nucleus of an atom. The number of protons in an atom determines its atomic number and therefore its nuclear charge.


The atomic number is the number of what in an element?

An element's atomic number is a count of how many protons are normally part of the element's nucleus. Since protons are normally the only particle in the nucleus with a charge (+), the atomic number also represents the charge of the nucleus.


What is the effect on the mass number and charge of a nucleus when it loses alpha particle?

Whwn an alpha particle is lost we lose 2units of +ve charges and 4 units of mass no. So we are left with mass no.(M-4) and charge (C-2) M=initial mass no. C=initial charge Here 1 unit of charge used is= 1*1.6*10^-19 coulomb
