The learners sell 340 vetkoek for 15 weeks. They charge R12.00 for each vetkoek. Calculate the profit they will make if the cost for each vetkoek is RA.00 and the costs of all ingredients is R623.48 per week. Use the profit calculated in 3.1 and as well as the other funds to be determine if the money made is enough or not, to subsidize the farewell. Write down three facts of advice that you can give to other learners who would wan to engage in a fundraising activity,​

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.
