A student did the reaction below in the lab and produced 2 grams of PH3 using 6.2 g of hydrogen. 2 grams represents the

P4 (g) + 6H2 (g) --> 4PH3 (g)
Group of answer choices

percent yield

theoretical yield

actual yield

excess yield

Ithink is a because if say increased in electronegativity

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
