The table below gives some characteristics of element y. characteristics of element y values mass number 11 number of neutrons in a single atom 6 average atomic mass (grams/mole) 10.81 what is the identity of element y? c b na s

Answer is: the identity of element Y is B (boron).

A(Y) = 11; mass number.

A = p⁺ + n°; mass number is the total number of protons and neutrons in a nucleus.

n°(Y) = 6; number of neutrons in atom Y.

p⁺(Y) = A(Y) - n°(Y).

p⁺(Y) = 11 - 6.

p⁺(Y) = 5; number of protons in atom Y.

Z = p⁺; atomic number.

Atomic number is the number of protons, which is characteristic of a chemical element, boron is an element with atomic number 5.
