Conductors, most metals for example, valence electrons of the atoms can be localized with very little input of energy. Insulators, most non-metals for example on the other hand, offers high resistance to flow electrons through them. In insulators valence electrons of the atoms are tightly bound and therefore at low voltages there is no flow of electrons through them.
A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.

No, radiant energy and sound waves are not the same. Radiant energy refers to electromagnetic radiation such as light and heat, while sound waves are mechanical waves that require a medium, such as air or water, to propagate.

False. Feminine words end in "a" while masculine words end in an "o"

It means "true." The form with -ae indicates that it is modifying a feminine noun in one of the following cases:1) genitive singular: "of a true" something2) dative singular: "to a true" something3) nominative plural: "true" somethings (as the subject of a sentence)4) vocative plural: "O true" somethings!
True. Carbon dioxide is a nonpolar molecule because its linear molecular geometry and symmetrical distribution of polar covalent bonds result in a net dipole moment of zero. This means there is no separation of charge within the molecule.
