Valence electrons are important because these are the only electrons involved with an atom's
a. charge.
b. nuclear behavior.
c. chemical reactivity.
d. radioactive properties.

Find the empirical formula of each of the following compounds. given mass or for each element in a sample of the compound 3,611 g ca; 6.389 g c1

Which is true of transition metals when moving from left to right on the periodic table? the d sublevels are not filled across the period. the cation radii become larger across the period. atomic radii increase slightly and then start to decrease. atomic radii decrease slightly and then start to increase. o

Ineed ! i have no clue how to do this problem.
