A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio arranged in a defined manner through chemical bonds. They contain only one type of molecule.

A compound contains molecules of various components synthetically joined together in a fixed ratio.An component is an unadulterated compound substance made of same sort of iota.

CompositionCompounds contain various components in a fixed proportion organized in a characterized way through synthetic bonds. They contain just one kind of particle. Components that make the compound are artificially combined.Elements contain just one sort of iota. Every particle has a similar nuclear number i.e., similar number of protons in their core.

Capacity to break downA compound can be isolated into less difficult substances by synthetic strategies/reactions.Elements can't be separated into less difficult substances by compound responses.

TypesA tremendous, essentially boundless, number of substance mixtures can be made. Mixtures are ordered into sub-atomic mixtures, ionic mixtures, intermetallic mixtures and complexes.There are around 117 components that have been noticed. Can be named metal, non-metal or metalloid.

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

$_a^z\textrm{x}\rightarrow _{a-2}^{z-4}+_2^4\alpha$

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

$_a^z\textrm{x}+_{-1}^0\textrm{e}\rightarrow _{z-1}^a\textrm{y}$

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases $\gamma -radiations$ . this process does not change the mass number.

$_a^z\textrm{x}^*\rightarrow _a^z\textrm{x}+_0^0\gamma$

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as $\beta ^+$ -decay. in this the mass number remains same.
