Which of the are not true in regarding to atomic raqdii of main group elements.
a. atomic radii generally increase as you move from left to right across a period
b. atomic radii size is related to the number of electrons in the valence level and the number of protons in the nucleus.
c. atomic radii decrease size when the pull of electrons forward the nucleus of an atom is greater
d. atomic radii generally increase as you move down a group

a basic solution is an aqueous solution containing more oh-ions than h+ions. in other words, it is an aqueous solution with a ph greater than 7. basic solutions contain ions, conduct electricity, turn red litmus paper blue, and feel slippery to the touch.

explanation:

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
