The atomic number is the same as the number of protons.
Valence electrons determine the reactivity of the element.
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
The common ion charge of an element, Z, can be determined by looking at its position on the periodic table and its group number. Elements in the same group tend to have the same common ion charge due to their similar electron configurations. You can also refer to a periodic table to determine the common ion charge of element Z.

In order to appear on the periodic table a substance must be an element, consisting of only one type of atom with a given number of protons in its nucleus. This number, called atomic number, is unique to each element.
The atomic number is the same as the number of protons.
Oxidation numbers do not determine if an element is a metal or a nonmetal. The classification of an element as a metal or a nonmetal is based on its position in the periodic table and its physical and chemical properties. Metals are typically found on the left side of the periodic table, while nonmetals are found on the right side.
Valence electrons determine the reactivity of the element.
The atomic number is the number of protons in the nucleus of an atom. It determines the element's identity and its position on the periodic table. The atomic number of an element can also help to determine its chemical properties.
34
Valence electrons determine an element's chemical properties, such as its reactivity and ability to form bonds with other elements. The number of valence electrons also influences the element's position in the periodic table and its likely bonding patterns.

The identity of an element is determined by the number of protons.
To determine if a gas valve is in the on or off position, you can look at the position of the handle or lever. If it is parallel to the pipe, the valve is in the on position. If it is perpendicular to the pipe, the valve is in the off position.
Determine the grade of the position.
