Select all true statements from the following:

a. ) Metals are good conductors of heat and electricity.
b. ) Nonmetals generally react by forming covalent bonds (i.e. sharing electrons) or by gaining electrons to form anions.
c. ) Halogen atoms have the highest ionization energies amongst all groups in the periodic table.
d. ) All nonmetal atoms release energy when forming a 1- anion.

Is the following thinking correct?

a) Metals are good conductors of heat and electricity.
True

b) Nonmetals are generally not reactive.
Sometimes true. The coinage metals (i.e. Cu, Ag, Au, Pt) are not very reactive. Alkali metals are extremely reactive.

c) Metals generally have lower ionization energy than nonmetals.
True. The electrons of metals are easily removed.

d) All nonmetal atoms release energy when forming a 1- anion.
True for halogens. The addition of an electron to an atom to make the anion results in a product with a lower energy. Also look at the heats of formation of anions in aqueous solutions. All are negative, indicating that energy is released.

Is the following thinking correct?
This question was answered below by me and by GK. You may want to scroll down the page. It was posted by Nathan.

a) Metals are good conductors of heat and electricity.
True OK

b) Nonmetals are generally not reactive.
Sometimes true. The coinage metals (i.e. Cu, Ag, Au, Pt) are not very reactive. Alkali metals are extremely reactive.
Some of what you say is true but it doesn't answer the question. In addition, the coinage metals are metals and not non-metals.

c) Metals generally have lower ionization energy than nonmetals.
True. The electrons of metals are easily removed.
Again, much of what you have said here is correct; however, it doesn't anwer the question.

d) All nonmetal atoms release energy when forming a 1- anion.
True for halogens. The addition of an electron to an atom to make the anion results in a product with a lower energy. Also look at the heats of formation of anions in aqueous solutions. All are negative, indicating that energy is released. See what GK and I wrote below.
