true
No. This is a definition of an atom. Electrons are only part of atoms.
Well I'm not sure if I understand your question but it's divided up like this Molecule, then Atom then, neutrons electrons and protons. ---------------------------------------------------------------------------------- The smallest unit of any element is an atom of that element. The smallest unit of any compound is a molecule of that compound (molecules are made of atoms)
No atom has the same number of protons as another atom, unless both atoms are atoms of the same chemical element.
False. Elements have different numbers of valence electrons, which determines their reactivity and chemical properties. The valence electrons are the electrons in the outermost energy level of an atom.
Atom
The element hydrogen is the simplest atom and the most abundant in the universe. It is composed of one proton and one electron.
Yes. It is true. An atom with a different atomic number is an atom of a different element.
yes it is true.
The simplest particle of an element is an atom. This is the form in which any element can be fully divided into without losing its properties.
A piece of pure Iron contains only one type of atom (Iron atoms) but there is more than one atom in it.
The simplest form of an element is an atom. Subatomic particles are not a form of the element; they are a "building block" of an element.
True. The number of atoms in a mole of an element is determined by Avogadro's number, which is a constant (6.022 x 10^23) regardless of the element being considered. Each element's molar mass in grams is equal to one mole of that element's atoms.
