Answer:
A
Explanation:
I would say a because we all know that kinetic energy is energy in motion and fuel is an example of chemical energy. So it must be from chemical to kinetic energy.
I'm not so sure but I would say it could be an iconic bond!
<em>Here is the Answer I Hope this Helps:-</em>
<em>The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom.</em>
B3+ is isoelectronic with helium.
Isoelectronicity is the phenomenon whereby two or more molecular entities have the same number of electrons or similar electronic configuration regardless of the nature of the elements that are involved.
In the question given above, helium and B3+ have the same number of electrons. Helium has two electrons. Boron has five electrons but it has given away three of the electrons [that is why it has a charge of +3] and it now has only two left.
Answer:
Osmium, 22.6 g/cc.
Iridium, 22.4 g/cc.
Platinum, 21.45 g/cc.
Rhenium, 21.2 g/cc.
Uranium, 20.2 g/cc.
these are are metals having a high density
