Chemical reactions depends on the valence electrons.
electrons
The number and arrangement of electrons in the atom's electron cloud determine its chemical properties. Electrons are involved in chemical reactions as they interact with other atoms. The number of protons in the atom's nucleus also plays a role in determining its chemical properties by defining its atomic number and identity.
chemical property
Electrons determine the chemical properties.
The atom is the smallest unit of matter that retains its chemical properties. It is composed of a nucleus containing protons and neutrons, surrounded by electrons that determine the chemical behavior of the atom.
The chemical behavior of an atom depends mostly on the number of electrons in its outermost shell.
This is the number of protons.
The smallest part of an element that retains all its properties is an atom. Each atom is made up of protons, neutrons, and electrons that determine the chemical behavior and physical properties of the element.
The electrons control the chemical properties of an atom. More specifically, the outer electrons, or valence electrons, are involved in bonding, and they determine the chemical properties of an atom.
Electrons orbit the nucleus of an atom and carry a negative charge. The number and arrangement of electrons determine an atom's chemical properties.
Valence electrons determine an atom’s reactivity and ability to form chemical bonds with other atoms. The number of valence electrons also influences an atom’s physical and chemical properties, such as its melting and boiling points.
An atom is the smallest particle of copper that still retains its chemical properties. Each copper atom consists of a nucleus containing protons and neutrons, surrounded by electrons that determine its chemical behavior. At this scale, further division would result in breaking the atom and changing the fundamental properties of copper.
