Answer True or False for each of the following:

a) Metals tend to have higher ionization energy than nonmetals.

b) The hydrogen atom is stable when it has a full octet of electrons.

c) The number of electrons domains (overall geometry) in PH3 molecule is four.

d) Excitation of an electron from 5s orbital to 4d orbital is endothermic.

Expert Solution

a) Metals tend to have higher ionization energy than nonmetals -------------> false

reason: metal easily loose electrons form cation readily . so metals have lower IE than non-metals

b) The hydrogen atom is stable when it has a full octet of electrons -------------> false

reason : because hydrogen atom cannot acheive octet configuration in its outermost shell . it has only one 1s orbital in it . it will maximum get 2 electrons

c) The number of electrons domains (overall geometry) in PH3 molecule is four.-------------> true

d) Excitation of an electron from 5s orbital to 4d orbital is endothermic.-------------> true

Answer True or False to each of the following. Write the answer in the column on the right. The width of the confidence interval is the margin of error. If a test is run and p=0.04, then we can reject H0 at ?=0.01. If a 95% CI for the difference in two independent means is (-4.5 to 2.1), then the point estimate is -2.1. The difference in means between two groups can be statistically significant, but not clinically significant. The...

True False Ionization energy is the energy released when an atom forms a negative ion. True False Ionization energy values may be either positive or negative. True False Electron affinity is based on the observation that electrons are attracted to other electrons. True False Electronegativity is a measure of the relative tendency of an atom to attract the electrons of a chemical bond in which it participates. True False Electron affinity is the amount of energy required to add an electron to a neutral atom...

Are the following statements true or false? In each case, prove your answer. There is a strictly decreasing function f from N to N with f(0) = 100. Let f(x) and g(x) be strictly increasing functions from R to R. Then (f + g)(x) is also strictly increasing. Once again, let f(x) and g(x) be strictly increasing functions from R to R. Then (f×g)(x) is also strictly increasing.
