Answer 1

Answer:

p = number of protons = atomic number

p = 5 (given)

Therefore, the specie X is Boron because the atomic number of Boron is 5 .

Answer 2

Answer:

number of protons=number of electrons in an atom

vallancy of x=2,3 (Boron)

vallancy of y=2,8,3 (Aluminium)

so y lose its valence electrons easily because it is more far away from nucleus than of x

so y applies less control on its valence electrons than of x

so y

please mark me as brainlist it is too important for me
