I do think that they are molecules.
molecules
OH -Is the polyatomic ion hydroxide and is covalently bondedNa + and OH -Make up the ionically bonded compound sodium hydroxide.
Compounds are made of elements. Elements are the smallest units of the compounds. Elements are bond to make compounds.
Many elements can form ionic and covalent bonds.With metals the non metals generally form ionic bonds- but with other non-metals they form covalent bonds. Examples:- The halogens (group 17) are covalent diatomic molecules, e.g. F2, Cl2 but generally form ionic compounds with metals . Oxygen forms ions, O2- in metallic oxides but bonds covalently to hydrogen in water nitrogen in ammonia, sulfur in H2S etc hydrogen forms the hydride ion in compounds such as LiH but bonds covalently in water and when bonded to carbon nitrogen forms the N3- ion in compounds such as Li3N but bonds covalently with oxygen in nitrogen dioxide.
nothing helium will not bond with anything and there for can not create a compound But there may be a few derivatives of a metastable F HeO- anion, in which helium is covalently bonded to oxygen.
molecules
table salt is NaCl and carbon dioxide is CO2 they are nothing a like. one is ionicly bonded(NaCl) and the other is covalently bonded
Carbon Dioxide (CO2). Compounds tend to be made from 2 or more different elements bonded together either covalently or ionically. They are all made of 2 or more elements bonded together whether those elements are the same or not. The other options are elements (Fe, O, and Ca respectively). They are not bonded to anything and therefore do not make a compound.

3: In a sort of triangle-with-no-base orientation, two hydrogen atoms are bonded covalently to an oxygen atom.

When atoms bond together they make molecules or compounds, depending on if the atom bonds with another atom of the same species or a different chemical
Yes, it is a diatomic element, a diatomic molecule. Some examples:O2 gasBr2 liquidI2 solid
Monomers are similar identical units covalently bonded to each other to from polymers. The monomer of carbohydrates are monosaccharides. Carbohydrates are polymers so its monomer is a simple sugar called monosaccharide.
So basically an atom of water or (H2O) is made up of two hydrogen atoms and one oxygen atom that are covalently bonded together to make a compound. A covalent bond is when two nonmetal elements, most commonly, two gases come together to make a compound. So water is a covalent bond because it is hydrogen bonded with oxygen which are both nonmetal elements being bonded together to form a covalent bond. There is a difference between ionic bonds and covalent bonds. The difference between an ionic bond and a covalent bond is that in a covalent bond the two or more elements that are being bonded together share electrons rather than take them like in an ionic compound. So with the fact that covalently bonded compounds share electrons in mind, electrons are not evenly distributed or shared throughout a water molecule because oxygen atoms strongly attract electrons. Because the oxygen atoms do this they pull electrons away from the hydrogen atoms giving them a partial positive charge. Now that the oxygen atom has the electrons closer to it than the other two hydrogen atoms it gives the oxygen atom a partially negative charge. This act of atoms not evenly sharing electrons is called a polar compound. What is special about compounds that are polar is that is attracts both positive and negative ions of an ionic commpund. Thats why water can dissolve ionic compounds because its polar structure.
