which of the following elements does NOT form bonds easily because it has a full outer shell?

Question

a. aluminum
b. carbon
c. helium
d. calcium

Answer 1

I'm pretty sure it's Helium. Helium is a member of the "noble" gases or sometimes called as the inert gases group (the right most column of the periodic table). They are such called inert gases because they have a complete octet (meaning its outermost shell is full of electrons) making it stable and unreactive in normal conditions.

The reason why most elements would react is because they have an incomplete outermost shell. Hence they have to react with other elements in such a way that they would acquire a greater stability by losing or sharing their electrons.

Having said that, helium is a relatively stable element since it has a full outermost shell thus making it unreactive on normal conditons. Under extreme conditions (high temperature and high pressures) however, helium can form bonds and react with other elements.

Hope this helps. =)

Answer 2

The answer can be found easily in the periodic table. Just look at the elements on the furthest column to the left. All of these elements have 8 electrons in the outermost shell, which is the maximum number for the outermost shell. Helium is one of them.

Answer 3

helium n don't go for the full filled shell go 4 molecular orbatal theory ne ways if beginer try to find the answer from perodic table n full filled shell theory only best of luck

Answer 4

all but helium form bonds really easlily. Carbon has the most availble bonds to form.

It appears like your spouse is a self-typical, egocentric brat. it rather is all approximately her. you need to make certain a funds. while each little thing is paid for the month, and money is desperate aside for the newborn's footwear, and a few in fee reductions, what's left? i be responsive to, possibly no longer plenty. except you are able to decrease down on expenses someplace else, that's what you have for leisure. while she is chuffed and contented, set her down, and go over it along with her. clarify and teach it to her in black and white. it rather is what's coming in and going out. in case you thieve from Peter to pay Paul, what are you going to do approximately Peter? you have X quantity of greenbacks to spend on video clips, eating out, etc. it rather is all.
