Chemistry Questions and Answers
Explain why atomic radii decrease as you move from left to right across a period. -
answer The atomic radii decrease as you move from left to right across the periodic
table because you are adding electrons and protons to gain more electrostatic
attraction.

Explain why it takes more energy to remove the second electron from a lithium atom
than it does to remove the fourth electron from a carbon atom. - answer It takes
more energy to remove the second electron from a lithium atom than it does to move
the fourth electron from a carbon atom because the second electron is closer to the
nucleus with no shielding and the fourth electron is farther away from the nucleus and
has shielding.

Some sports bottles are made of Lexan, a plastic containing a compound of the
elements chlorine, carbon, and oxygen. Order these elements from greatest to least

Does fluorine or bromine have a larger electronegativity - answer fluorine

Does fluorine or bromine have a larger ionic radius - answer bromine

Does fluorine or bromine have a larger atomic radius - answer bromine

Does fluorine or bromine have a larger ionization energy - answer fluorine

If A is an ion and B is an atom of the same element, is the ion a positive or negative
ion? - answer The ion is negative because a negative ion is always larger than its
atom.

If A and B represent the atomic radii of two elements in the same period, what is their
order? - answer A is to the left of B because the atomic radius in a period decreases
left-to-right.

If A and B represent the ionic radii of two elements in the same group, what is their
order? - answer A is below B because ionic radius increases down a group.
