Just making sure, first off, that you realize electrons are not in the nucleus.
They float in the empty space around the nucleus, of an atom.
But if your asking what happens to the atom once it loses an electron, the atom then has a positive charge, and becomes a positive ion.
The atomic size[of the atom alone] becomes smaller due to the greater pull the protons are able to have on the electrons.
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.
An electron has a charge of -1. When a Sodium (Na) atom loses one electron, it loses a negative and becomes a stable Sodium ion with a charge of +1.
When cesium forms an ion, it loses one electron to become Cs+ with a full outer electron shell. This results in the formation of a cation with a positive charge due to the loss of one electron.
When an atom becomes an ion, it gains or loses electrons to achieve a full outer electron shell, resulting in a change in electron configuration. For example, a neutral sodium atom (1s2 2s2 2p6 3s1) loses one electron to become a sodium ion (1s2 2s2 2p6). The electron configuration of the ion reflects this change in the number of electrons.
Na+ gains one electron to become Na:1+ and Cl- loses one electron to become Cl1-.

Potassium loses one electron.
An atom that loses one or more electrons becomes positively charged, because the number of protons (+) in the nucleus will outnumber the electrons (-).
An electron has a charge of -1. When a Sodium (Na) atom loses one electron, it loses a negative and becomes a stable Sodium ion with a charge of +1.
To change a lithium atom (Li) to a lithium ion (Li⁺), you need to remove one electron from the outermost shell of the lithium atom. This process typically occurs in a chemical reaction or through ionization, where energy is supplied to overcome the attraction between the negatively charged electron and the positively charged nucleus. As a result, lithium loses one electron, resulting in a positively charged lithium ion (Li⁺).
When cesium forms an ion, it loses one electron to become Cs+ with a full outer electron shell. This results in the formation of a cation with a positive charge due to the loss of one electron.

When lithium loses one electron, it forms a lithium ion with a +1 charge. This ion has the same number of protons (positive charge) as electrons (negative charge) in its nucleus, giving it an overall charge of +1.
Potassium loses one electron. All Alkali metals lose one electron.
Na+ gains one electron to become Na:1+ and Cl- loses one electron to become Cl1-.
The hydrogen atom has one proton as its nucleus and one electron orbiting around the nucleus.
An atom that loses one electron is called a cation. When an atom loses an electron, it becomes positively charged due to the imbalance between the number of protons (positive charge) and electrons (negative charge). For example, when a sodium atom (Na) loses one electron, it forms a sodium cation (Na⁺).
