inysia [295]

Answer is: 2. atomic number.

Atomic number is unique and defines an element. Atomic number (Z) is total number of protons in an atom.

For example, nitrogen atom (N-14) has 7 protons (p⁺), 7 electrons (e⁻) and 7 neutrons (n°). Protons (positive charge) and neutrons are in the nucleus of atom, electrons (negative charge) are bound to the nucleus in spherical shells.  Nitrogen is an element with atomic number 7.                                                       Mass number (A) is the total number of protons and neutrons in a nucleus. Nitrogen mass number is 14 (A = p⁺ + n°; A = 14).

How to define chemical and physical changes?

Chemical Change-

Any alteration that produces new chemical substances with distinct properties is considered a chemical change. Chemical reactions involve the rearrangement and recombination of elements and compounds to create new substances. Examples of chemical changes are listed below:

  • Burning
  • Digestion
  • chemicals changing colors
  • Tarnishing
  • compost rotting

Physical Change-

A substance is not destroyed or transformed into something new by physical changes. A substance can undergo physical changes that alter its shape, size, or phase. The constituents of an element or compound do not change during a physical change. Examples of physical changes are listed below:

  • Boiling water
  • Chopping, Cutting, Carving
  • Evaporation
  • Freezing, Melting, Condensation
