As you move across the periods from left to right on the periodic table, the atomic radius decreases. why?
a. the valence electrons are located further away from the nucleus so they experience less effective nuclear charge.
b. the effective nuclear charge increases and pulls the valence electrons closer to the nucleus.
c. the valence electrons are found in higher energy levels.

Non renewable resources like petroleum eventually

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.
