Such unit is molecule.
An electrically neutral particle composed of two or more atoms chemically combined is called a molecule.
an electrically neutral atom is just an atom. Atoms with more or fewer electrons (negatively charged) compared with their protons (which determines the element) are considered ions.
an electrically neutral group of two or more atoms held together by chemical bonds.
The smallest electrically neutral collection of ions is called a formula unit. This is typically found in ionic compounds, where positive and negative ions combine to balance the overall charge to zero.
A neutral atom, in order to be neutral, has the same number of protons and electrons. If the atom gains or loses an electron, or more than one, it will become electrically charged.
a charged group of two or more nonmedal atoms is called a?
A molecule is an electrically neutral group of two or more atoms held together by covalent chemical bonds.
atoms, molecules, neutrons, photons, neutrinos and many more
I think you're talking about an isotope. An Isotopes are two or more forms of the same element that contain equal numbers of protons and electrons but different numbers of neutrons. Therefore they have similar chemical properties but differ in atomic mass. I hope this helps you :)
The name of this combination is - molecule.
Yes, most atoms do have more electrons than protons. This is because atoms are electrically neutral, and the number of protons (positive charge) in the nucleus is balanced by the number of electrons (negative charge) surrounding the nucleus.
In chemistry, a molecule is defined as a sufficiently stable electrically neutral group of at least two atoms in a definite arrangement held together by very strong chemical bonds. It can also be defined as a unit of two or more atoms held together by covalent bonds.
