Answer:
O, S, Se, Te, Po
Explanation:
Oxygen, sulphur, selenium, tellurium and polonium are all members of group sixteen. The elements in group sixteen all possess six electrons in their outermost shell. Recall that an atom is said to stable if it contains eight electrons in its outermost shell. This is also referred to as the octet rule. Hence atoms of elements obey the octet rule when they combine to form compounds with eight electrons present on the outermost shell of each atom.
Having six electrons on their outermost shell implies that they need to gain two electrons by bonding to other atoms of other elements. Two examples will suffice here.
Water is formed when an oxygen atom shares an electron with each hydrogen atoms.
Hydrogen sulphide is formed when sulphur share two electrons with two hydrogen atoms. Hence the answer.
There doesn't seem to be a clear answer, it is placed in the center when it's substances is on the corners it doesn't give anything else
Answer:
i think the answer is A
Explanation:
because in some areas, a regular pattern occurs of one high tide and one low tide each day,
Well because the lowest possibility of having a decen is 3-decene so 6-decene is not possible. Hope this helps!! :)
Answer:Liquids expand for the same reason, but because the bonds between separate molecules are usually less tight they expand more than solids.
Explanation:Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
