An element x has two isotopes. x–15 has 7 protons and 8 neutrons. determine the atomic number and mass number of the second isotope, which has 10 neutrons in its nucleus.. how would i do this and get the answer?

The atomic mass of the second isotope of an element X 17 amu with atomic number of 7 and it is represented by X-17.

Explanation:

Number of protons in isotope X-15,(p) = 7

Number of neutrons in isotope X-15,(n) = 8

Atomic mass of the isotope X-15 = (p) + (n) = 7 + 8 = 15 amu

Number of protons in second isotope of an element X,(p) = 7

Atomic number = Number of protons in an atom of an element

Number of protons in the isotopes of same element remains the same

Number of neutrons in second isotope of an element X,(n) = 10

Atomic mass of the second isotope of an element X= (p) + (n) = 7 + 10= 17 amu

The atomic mass of the second isotope of an element X 17 amu with atomic number of 7 and it is represented by X-17.

58750.08068 is the answer i think

i don't see a text, but i am gonna assume this *orbit* the curved path, usually elliptical, described by a planet, satellite, spaceship, etc., around a celestial body, as the sun.
