"Number" goes up by one, mass stays the same.
When a radioactive isotope emits a beta particle (high-energy electron), a neutron in the nucleus is converted into a proton. This causes the atomic number of the nucleus to increase by one because a proton has a positive charge and changes a neutron to a proton increases the atomic number.
It's been awhile for me, but this is how I remember it. It is not convenient for me to look it up right at the moment, so you may want to verify this. Emitting an alpha particle (2 proton 2 neutron), atomic number would decrease by 2 and atomic mass decreases by 4.Electron emission means a neutron turns into a proton and electron, but the electron shoots out. The atomic number increases by 1 and atomic mass stays the same. Proton emission, well it loses a proton. So the atomic number decreases and mass decreases.
Electrons collect in the outer energy levels of atoms, known as electron shells. These shells are organized around the atomic nucleus and can hold a specific number of electrons based on the atom's atomic number and electron configuration.
You will recall that electrons orbit the nucleus of an atom (or in quantum mechanical terms, they surround the nucleus as a cloud). Under some circumstances, one of those orbiting electrons can fall into the nucleus, where it will react with a proton and convert it into a neutron. This is an electron capture process.
The number of protons in the atomic nucleus determines the properties of an element. Every element has its own unique number of protons, called its atomic number, which is displayed on the periodic table. The elements are arranged in order of increasing atomic number on the periodic table.
Atomic number is the equivalent of the number of protons in an atomic nucleus.
Atomic number is the number of protons in the nucleus of an atom. Therefore, sodium's atomic number is always 11, even if it loses 1 electron. However, when a sodium atom loses 1 electron, it will form an ion with a 1+ charge.
The atomic number correlates to the number of protons found in the nucleus of an atom. The atomic number also dictates the number of electrons that orbit the nucleus if the atom in neutral. Finally the atomic mass is the number of protons and neutrons found in the nucleus. The atomic number equals the number of protons (p+) or electron (e-).
The atomic mass number represents the total number of protons and neutrons in the nucleus of an atom. It does not include the number of electrons, which are found in the electron cloud surrounding the nucleus.
The atomic number is the number of protons in a nucleus.

The atomic number is equal to the number of the protons in the atomic nucleus.
Is the number of protons or electron found in a given (neutral) element.
no of the protons or the no of electron is equal to the atomic no denoted by the symbol Z
The atomic number for hydrogen (H) is 1, and it has 1 electron in the outer shell.
what is the atomic number of the nucleus?
