The electrical charge is changed by -1 when an atom loses an electron. The Atomic Mass number is determined by the number of protons and neutrons in the nucleus and is unaffected by the loss of an electron.

In an element box, you will typically find the element's symbol, atomic number, atomic mass, and sometimes its electron configuration.
The Atomic Number of the element is equal to the number of electrons. Also, the number of protons is also equal to the Atomic number; so the number of protons and electrons in any given element is the same!
Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
The atomic number represents the number of protons in the element. This number is unique to that element, if you change the atomic number (number of protons) then you change the element.

1s2 2s2 2p6 3s2 3p3 is the electron configuration of element 15.
The spdf electron configuration for the element with atomic number 20 (calcium) is 1s2 2s2 2p6 3s2 3p6 4s2.
In an element box, you will typically find the element's symbol, atomic number, atomic mass, and sometimes its electron configuration.
For carbon, each element box contains the element's name, symbol, atomic number, atomic mass, and electron configuration. For hydrogen, the box includes the element's name, symbol, atomic number, atomic mass, and electron configuration.
The element with electron configuration 1s22s23p1 is phosphorus, which has an atomic number of 15.
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
The Atomic Number of the element is equal to the number of electrons. Also, the number of protons is also equal to the Atomic number; so the number of protons and electrons in any given element is the same!
Each column will generally have the symbol of the element (sometimes name of the element also), the atomic number, the mass number, the state in which the element is present at room temperature. Some periodic table will also have the electronic configuration or electronegativity.
Is the number of protons or electron found in a given (neutral) element.
The ground state electron configuration for the element with the atomic number corresponding to the keyword "fe" is Ar 3d6 4s2.
