The chemical nature of the substance.
The rare earths all have a similar 'outer shell', and differ only in their 'inner shells', hence the similarity of many of their properties.
The three factors determine the chemical properties of an element:The number and arrangement of electrons in an atomThe number of valence electronsThe number and arrangement of electrons
The number and arrangement of electrons in the outer energy level determine the atom's chemical properties, including its reactivity and ability to form bonds with other atoms. This outer energy level is known as the valence shell.
The number of electrons determines an element's position.
It depends on the number of electrons and protons the charge of an atom depends on the number of electrons and the number of protons
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
The number and arrangement of electrons.

The number of protons in the nucleus, which determines the element's identity, has the greatest effect on an element's properties. The number of electrons determines its chemical behavior, while the arrangement of electrons in energy levels plays a role in its physical properties.
The number and arrangement of electrons in the outer energy level determine the atom's chemical properties, including its reactivity and ability to form bonds with other atoms. This outer energy level is known as the valence shell.
The amount of electrons in each element.
The number of electrons in an atom determines its charge and is equal to the number of protons in a neutral atom. Electrons are arranged in energy levels around the nucleus, following the Pauli exclusion principle and Hund's rule. The number and arrangement of electrons determine the chemical properties and reactivity of an element.
ELEMENT
electrons in their outermost energy levels. The number of electrons in the outermost shell affects how atoms form bonds with other atoms. This arrangement determines the chemical reactivity and stability of the species.
The arrangement of electrons in atom shells determines the chemical properties of an element. It affects how atoms bond with each other to form molecules and compounds. The number and distribution of electrons in the shells also determine the element's reactivity and ability to participate in chemical reactions.
no . by the number of protons which determines the number of electrons when neutral
The subatomic particle that determines an atom's chemical properties is the electron. Electrons are involved in chemical bonding between atoms, which determines the reactivity and behavior of elements. The number and arrangement of electrons in an atom's electron cloud dictate how it interacts with other atoms.
The number of protons determines the number of electrons in the ground state of the atom. However electrons can be subtracted or added when the atom is not in its ground state, creating ions.
