Answer:
can you show me a picture of that element graph pls i dont really understand it
<span>Four orbitals are needed to contain six electrons if two electrons are unpaired. According to Hund's rule, degenerate orbitals are filled evenly. Electrons minimize the force of repulsion by orbiting at a distance.</span>
A. An element in its pure state is always 0.
B. One of the oxidation rules is that H with a nonmetal (which is Cl) is always +1. Cl would be -2 because -2 + (+1) equals -1.
C. Oxygen is always -2, so Cl- would have to be -1 to equal -3.
It has been awhile since I learnt this in AP Chem so answers could be a little rusty. Hopefully it helps.
Answer:
both melting point and boiling points are lower
this is because it becomes easier to break those bonds (they’re actually intermolecular forces) between the atoms sinc they’re weak, and thus require less energy to break.
