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.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.

the right answer is c i just did the question.
