The number following the name of the element is the number of subatomic particles inside the nucleus of the atom. This means that it is the mass number of the isotope. The average atomic mass of the element is the sum of the products of the percentage abundance and mass number of the naturally occurring isotopes.
Since, the average atomic mass of the hydrogen is nearest to 1 then, the most abundant isotope should be hydrogen-1.
Heating up, mostly. Solid can be heated to liquid, then to gas, then eventually to plasma.
Answer:
The halogens, nitrogen and sulphur are covalently bonded to the organic compounds. In order to detect them, the elements need to be converted into their ionic forms. This is done by fusing the organic compound with sodium metal. ... The extract is called sodium fusion extract or Lassaigne's extract.
Answer:
No question is posted.
But Ionic bond is mostly between metals live Na, K, Ca, Mg and strong non metals like Cl, O, F
Explanation:
Extrusive rock because it takes longer to cool, making the crystal size larger
