Can someone me with how to do this? ? i am lost

the question is, "find intersections and unions of the following given sets.

you.

G represents sets of student appearing for GENERAL KNOWLEDGE  

M represents sets of student appearing for MATHS

S represents sets of student appearing for SCIENCE

G ∩ M = { Max, Anael}

G ∪ S = { Max, Acel, Carl, Anael, Acton, Dario, Kai, Barek, Carlin}

bn,mn,n.vn.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
