atom, smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element. As such, the atom is the basic building block of chemistry.
Which is the smallest stable atom?
Helium is the smallest atom.
What is the first smallest unit of matter?
An atom is the smallest unit of matter that retains all of the chemical properties of an element.
Why molecule is the smallest unit of matter?
c) Molecule: Molecules are a group of atoms bonded together; representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction this implies that they can be further divided into atoms.
What is the smallest element?
Thus, helium is the smallest element, and francium is the largest.
Which is the smallest molecule?
The smallest molecule is the diatomic hydrogen (H2), with a bond length of 0.74 Å.
What is the smallest stable element in the product table?
helium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid at −268.9 °C (−452 °F).
Which is the smallest unit atom or molecule?
An atom is the smallest particle of an element while the molecule is the smallest particle of a compound.
