Aneutral group of atoms held together by covalent bonds is a

Molecule

Explanation:

A molecule is a particle made up of two or more atoms held together by chemical bonds. A molecule is different from an ion because it does not carries a charge. Molecules are chemically bonded together by either covalent bonding or ionic bonding. A covalent bond involves the sharing of electron pairs between atoms. Examples of molecule with covalent bonding include H₂ and NH₃ . Therefore, a neutral group of atoms held together by covalent bonds is a molecule.

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
