The number of electrons is very important.
An atom is the smallest part of an element that displays the chemical properties of that element. Each element is defined by the unique number of protons in its atom's nucleus, which determines its chemical behavior.
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 valence electrons an element atom contains will determine its chemical properties.
Electrons.
Yes, every atom of an element possesses the properties that define that element. These properties include the number of protons in the nucleus, which determines its atomic number and chemical behavior. Whether in isolation or as part of a compound, each atom of an element maintains its unique identity.
The smallest part of matter that retains its own chemical properties is called a(n) _______.
The electron field.
The "extranuclear part" (interesting term, by the way) of the atom is, essentially, the electrons. The electrons determine the chemical properties (and, to a certain extent, the physical properties). So they're very important indeed.
Electrons. These electrons move in orbitals around the nucleus, which is the central part of the atom containing protons and neutrons. The arrangement of these electrons determines the chemical properties of the atom.
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 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.
Protons (the number of ..) determine the 'kind' of element,and the electrons in the outmost valency orbital determine the properties(the number of electron; and 'octet' rule: "make it eight preferably').
