Question

The atomic number of an element:

#1. Tells you the mass of the atom

#2. Tells you the number of energy levels there are around the atom

#3. Tells you the identity of the atom

#4. Tells you how many valence electrons the atom has

Answer 1

#3. Tells you the identity of the atom

Step-by-step explanation:

The atomic number of an element tells you the identity of the atom and indirectly provides information about the number of valence electrons. It does not directly tell you the mass of the atom or the number of energy levels.

Answer 2

I think #3 might be the answer .

Because in #1 atomic mass tells mass .

#4 Atomic number doesnot only tell about the electrons atom has
