An unknown atom has 26 neutrons and an approximate atomic mass of 48 amu. what is the name of this element?

Answer is: the name of this element is titanium (Ti).

n ° = 26.

A = 48, atomic mass.

The mass number A is sum of the atomic number Z and the number of neutrons.

A = n° + p⁺.

p⁺ = A - n°.

p⁺ = 48 - 26.

p⁺ = 22, number of protons.

Z = p⁺, atomic number.

The atomic number (proton number) uniquely identifies a chemical element.

Titanium is transition metal with a silver color.
