An atom with 7 protons, 6 neutrons, and 7 electrons has an atomic mass of amu. (enter a whole number.)

Answer : An atom with 7 protons, 6 neutrons, and 7 electrons has an atomic mass of 13 amu.

Explanation :

As we are give that,

Number of protons = 7

Number of electrons = 7

Number of neutrons = 6

As we know that,

Atomic number =Number of protons = Number of electrons = 7

Atomic mass = Number of neutrons + Atomic number

Atomic mass = 6 + 7 = 13 amu

Therefore, the atomic mass is, 13 amu
