Biting the hand that feeds me here... but 1030 is obviously 10^30. This is a common effect of moving between formats with different capacity for superscripts. The whole page uses this form fairly consistently for powers of ten.
As a crude estimate, the number is not bad. 10^29 would be better, but for a back of the envelope 10^30 is easier to remember.
Diamond has about 1.76e29 atoms per cubic meter. A quick look did not turn up anything with more atoms per unit volume.
Lead has about 3.3e28 atoms per cubic meter. Most solids will be somewhere between these two values.
