Carbon has three allotropes, diamond, graphite and buckminsterfullerene.
When atoms of more than one element chemically bonded together, they form a molecule. In some contexts, the you might answer that they form a compound.
Group one elements are generally more reactive than group two elements. This is because group one elements have one electron in their outermost shell, making them more willing to react and form compounds in order to achieve a stable electron configuration. Group two elements have two electrons in their outermost shell, which makes them less reactive than group one elements.
It is IMPOSSIBLE to form elements of any kind or group other than by nuclear processes. There is no special one for transition elements.
Copper (Cu) does not form more than one type of cation.
When different kinds of elements bond together, they form a compound. Compounds are formed through chemical bonding, where atoms of different elements come together to create a new substance with unique properties. Ionic and covalent bonds are common ways that elements can bond together to form compounds.
Yes, it is correct.

Transition metals are elements that can form ions with more than one charge. This is because they have multiple oxidation states due to the variety of ways in which they can lose electrons from their outer shell. Examples include iron (Fe), copper (Cu), and chromium (Cr).
elements exist in more than one form eg carbon 12 and carbon14
Elements form molecules of chemical compounds
one or more elements combine to form compounds

Transition metals contain atoms that form colored ions and have more than one positive oxidation state. Examples include chromium, manganese, iron, cobalt, copper, and nickel.
There are a bit more than 100 elements however there are far, far more than 100 millions compounds, each day more compounds are produced, there are a lot of compounds with unknown structure, not having official names. So the ratio is much bigger than 1 to a million
More than one thrombus (or the plural form) is "thrombi".
Members of groups 1, 2, 6, 7 in the Periodic Table are most likely to form ionic compounds. It depends on what pair of elements are involved, for instance one rule of thumb is metal with nonmetal. Another, more systematic way, to assess this is to consider the difference in electronegativity between the two elements. If the electronegativity difference is 2 or more then the bond will be ionic. If the difference is less than 2 but more than 1.6 and one of the elements is a metal then there can be an ionic bond.
