electrons
Revolving around the nucleus at a distance is a cloud of particles called electrons. Each electron has a negative charge.
I believe the most massive element that is naturally occurring on Earth is uranium (U), which has a nucleus of 92 protons
<span>Best Answer: Mn(ii) is catalyst
Stetep-1 is slow step
Steps-2,3 are fast steps
intermediates are Mn(iii)and Mn(iv)
since step -1 is slow rate depends on Ce(iv) and Mn(ii) only
not on Tl(i) as it is involved in fast step-3</span>
amount of charge producing a field (direct)
the distance from the charge (inverse)
An empirical formula is a molecular formula D. reduced to the ratio of atoms involved.
An empirical formula has simplefied ratios, which makes it easier to work with. However, the accuracy is not that good
hope this helps
