what type of elements usually react to form molecules?

Answer 1

The word molecule tells you that it is a covalent compound (if it were ionic, it would be called a unit cell). Covalent compounds are USUALLY between nonmetals but in some cases can be between a metal and a non-metal. It all boils down to electronegativity difference (how much harder one atom is pulling on the electrons in question than the other atom). I hope this helps!

Answer 2

If you're only considering molecules that are combinations of two of the same element, then there are only a few elements that will do that. They exist as diatomic molecules. Those elements are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine and iodine.

If you're just asking about any type of molecule, I think the best answer is that non-metals can react to form molecules. So, compounds like carbon dioxide or sugar are all molecules formed by non-metals reacting with other non-metals.

Hope this helps.

Answer 3

If ur talkin bout only one element bondin wif itself to make a molecule then it has to be a non-metal as to bond this way it has to bond covalently. Then of these element those which only exist as diatomic molecules are more likely to form molecules. examples of these elements are nitrogen (N2) and oxygen (O2).

However if you are talking about molecules of two different elements then:
firstly noble gases, found in group 8/0 will not react to form molecules as they have a full outer shell of electrons and it is due to this that elements react as they all want to gain a full outer shell. With this information non-metals in group 7 (the halogens) are more likely to react as they only require to GAIN one electron to make a full outer shell. With this information we can see that the element at the top of the group will be most reactive as the outer shell is closest to the positively charged nucleus and therefore (as electrons are negatively charged) it is easiest for them to attract another electron. In metals however it is the elements in group 1 as they only need to LOSE one electron to have a full outer shell. therfore those found near the bottom of the group are more likely to form molecules as the outer electron is the furthest from the nucleus and therfore the easiest to lose because the forces of attraction between it and the nucleus will be very weak.

Hope this helps.

Answer 4

The type of elements which form molecules are the non-metals when they combine with other non-metals. All their compounds are composed of molecules so, as long as there is no metal in the compound you can be sure it's made of molecules.
Note. Some of these molecules can form ions when dissolved in water.

Answer 5

An atom is smallest particle in a factor that has the properties of the element. Molecules are shaped by the combination of two or greater atoms. in assessment to atoms, molecules could be subdivided to man or woman atoms. wish this permits Victor

Answer 6

Reactive elements. Basically, the only group of elements that do not react are group 8 (Noble gasses). Every other group has spare electrons in the outter shell and will react with other elements.

Answer 7

most

some do more than others and some not at all (inert ones, like helium)

Some are very reactive - oxygen etc - and are in molecules all the time.

Other examples: Calcium, Carbbon, sodium, Magnesium, Iron

Answer 8

Reactive ones.
