A group of elements that rarely combine with other elements because they already have eight electrons in the outer shells is a Noble Gas
Electrons are shared when elements combine to form molecules.
Because they determine how the element will combine with other elements
Two elements combine together by sharing electrons to form a bond.
Okay Hi I am A Freshman and this question was really hard but i have the answer... they combine because they both want to have 8 electrons... so they share electrons and that bonds keep them together love,jade
The electrons get shared between the two elements, from the covalent bonds.
all the electrons that are available in outermost shell
Carbon, Geranium, Tin, and Silicon. The reason for this is because all of these elements including Lead, have four valence electrons.
Elements have a number of electrons in their outer shell of the atom, all elements want to have a full shell and usually form with other atoms to do so. However, Xenon is a noble gas and already has a full outer shell and so does not combine with other elements unless it is made to do so.
It is non-reactive because it's shells are full. Argon has three electron shells. It's third shell is filled with eight electrons. That is why it does not easily combine with other elements.
Electrons are shared when elements combine to form molecules. These are subatomic particles with a negative elementary electric charge.
elements combine to attain more stability, generally by attaining the electronic configuration of the nearest noble gases. they do so by donating electrons, accepting electrons or by sharing electrons
elements combine because no body noes :DBecause elements become ions then combine
