false because a compound has to have two elements to become a compound so if it's just one element it's just a element.
False
True
Is it true that in a relation for each element of the domain there is only one corresponding element in the range
No, this is false.
False
False. A molecule is the smallest part of a compound that can still be indentified as a compound as it may contain several atoms of different elements. A single atom can only identify a single element, not a compound which it may have been a part of.
No. This is a definition of an atom. Electrons are only part of atoms.
No, none of them contains only one element of art.
false a compound is made up of two or more elements.
False, because a compound is a pure chemical substance consisting of two or more different chemical elements. It can be separated into simpler substances by chemical reactions.
True. Very few rocks contain only a single compound or crystal.
A compound is different from an element in that a compound is made up of several elements. An element is a base atom only. Think of a compound as a living room set and an element as a couch only.
False, because the only element with the highest Electronegativity is hydrogen and the atomic number is 1.
An element is only a chemical element, only a single type of atoms.A compound contain 2 or more atoms of different atoms.Matter can be an element, a compound or a mixture of compounds.
True.
Iron is the major element in steel. Only an element can be an element, and an element can not be a compound, the definition of which requires more than one element.
Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
