The atomic number
The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It determines the element's identity and its position on the periodic table. Elements with different atomic numbers have different chemical properties.
The atomic number is the number of protons, so 15.
The atomic number of an element represents the number of protons in the nucleus of an atom. It is a unique identifier for each element on the periodic table. The number of protons in an atom determines the element's chemical properties and its place in the periodic table.
The atomic number is the one number that identifies an element. It represents the number of protons in the nucleus of the atom, which determines the element's properties and place on the periodic table.
The atomic number is the number of protons in an element. Ex: Molybdenum's A.N. is 42. so it has 42 protons.
The atomic number represents the number of protons. The atomic mass represents the number of protons + neutrons.
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.
An element's ID number is the atomic number, which represents the number of protons in the nucleus.
The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It determines the element's identity and its position on the periodic table. Elements with different atomic numbers have different chemical properties.
The atomic number of an element represents the number of protons in the nucleus of an atom of that element. It determines the identity of the element on the periodic table and distinguishes it from other elements.
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
It represents the number of Protons (p+) that element has in the nucleus of one atom.
... of protons in the nucleus of each atom of the element.
The atomic number represents the number of protons in the nucleusNumber of protons in nucleus.Number of electrons in the clouds around the nucleus (when not ionized).
The atomic number represents the number of protons in an atom's nucleus. It determines an element's unique identity and its position on the periodic table. Elements with the same atomic number are the same element, regardless of their isotopic variations.
It represents the number of protons and the number of electrons in an atom of the element.
It represents the number of protons and the number of electrons in an atom of the element.
