Ionic compounds are generally made up of nonmetals and metals, while molecular compounds are normally made up of nonmetals only.
I'm not sure what you mean by "purely covalent", since the ionic-vs-covalent distinction is expressed in terms of electronegativity, which can take a range of values (higher values = more ionic). CO is very much a covalent compound though.
how many electrons it has in its valence shell usually also some of the characteristics... eg. alkali metals vs. noble gases etc.
Covalent is two non-metals sharing electrons while Ionic is a metal and a nonmetal where one takes an electron and changes both of the elements charges for example Nitrogen and Oxygen would be covalent while Iron and Oxygen would be Ionic
An ionic compound is formed between a metal and a non-metal. Zinc is a metal and iodine is a non-metal. Zinc needs to lose two electrons in order to have a full outer shell, and iodine needs to gain one electron to have a full outer shell. One zinc atom will form a positive ion (Zn2+), and two iodine atoms will gain one electron each from the zinc atom, forming negative ions (I-). As such, the chemical formula of zinc iodide is ZnI2. The equations below demonstrate this.Zn --> Zn2+ + 2e-2I + 2e- --> 2I-
according to MOT each energy level can be occupied by 2 electrons which must have opposite spins these pairs of electrons considered to occupy molecular orbital. so molecular orbital is formed from the overlap of the atomic orbitals of the atoms making up the bond.
mechanical characteristics can be drawn between speed and torque electrical characteristics are 1. Output power vs speed 2. Output power vs input power 3. Output power vs efficiency 4. Output power vs torque 5. Output power vs line current

Key biographical characteristics include such things as education, previous work experience, and criminal convictions if any. Key personality attributes include such things as intelligence vs. stupidity, honesty vs. dishonesty, and responsibility vs. irresponsibility. For some types of work we could add creativity vs. lack of imagination.

I think what you mean is Mg(OH)2 vs MgO2H2. This is an ionic compound because it has a metal (magnesium). In it, Mg+2 is the cation (positive ion) and OH- is the anion. Because an ionic compound must have a zero net charge, there needs to be two OH- ions to cancel the +2 charge of the magnesium. so in the first formula it is shown that there are two OH- ions, but the second one is incorrect because OH is one ion and the elements are not separately written like that in an ionic compounds formula. hope this helps

Usually, the one that is solid has a higher molecular weight
dc series motors are used because of torque vs speed characteristics.
Yes...though there are several different compounds termed iron sulphide that have different stoichiometries [atomic proportions] and/or crystal structures. For example pyrite [FeS2] vs. troilite [FeS] are different compounds, though both are "iron sulphide".
The nature vs. nurture question asks whether differences in traits and behaviors are due to genetics (nature) or environment (nurture). It explores the influence of genetics and upbringing on a person's development and characteristics.
