Which is the thermally unstable compound?

Answer 1

A compound is a group of two or more elements

Unstable means it is highly reactive, and can condense, decompose, polymerize, or become self-reactive quite easily due to pressure or temperature

Answer 2

An unstable nuclide is a nucleus of an atom that has an unstable proton to neutron ratio and will therefore go through a process of decay until it reaches its 'ideal ratio', which is the ratio between protons and neutrons at which an element is most stabl.

Also, a nuclide could be unstable when having number of protons more than the maximum limit for number of protons for a nuclide to be stable. All nuclides with number of protons more than 83 are unstable and are naturally radioactive.

Answer 3

Substance may be classified as stable substance or unstable. You can say that it is unstable when it didn't reach the requirement of the rule of eight or octet rule which is to have 8 electrons in one element.

Answer 4

An unstable element is one whose nucleus decays, changing the element into another element. Examples of unstable elements are uranium and plutonium.

Answer 5

Which is a stable compound? LiH2, BeH2, BH2, CH2

------------------------------------------------------------------------------

Note: only BeH2 is a true chemical compound !

Answer 6

H2O, HF, KCl, NaOH, (C2F4)n, C6H12O6...wouldn't it be easier to list the unstable ones?

Answer 7

hgo na2o h2o co2

Answer 8

Examples: NaCl, U3O8, ThO2, LiBr etc.
