Nonmetallic elements form ions by valence electrons to complete their outer shell. the valence electrons an element has in its outer shell, the easier it is to complete. the electron shells an element has, the easier it is to fill its outermost shell. reactivity in nonmetals as you go from left to right in a group, and as you go from top to bottom.

Calculate the ratio of h+ ions to ohβ ions at a ph = 6. find the concentration of h+ ions to ohβ ions listed in table b of your student guide. then divide the h+ concentration by the ohβ concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to ohβ ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of ohβ ions at a ph = 6? mol/l what is the ratio of h+ ions to ohβ ions at a ph = 6? : 1

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
