Answer: There will be 9.9632 × 10⁻¹⁸ moles of Copper in 6,000,000 atoms of Copper.
Each half-life results in ~50% (1/2) of the original element remaining.
7500/1250 = 6 half-lives, so 100(1/2)^6
= 100(0.015625)
= 1.5625% of the original element would remain
<span>Since the diploid number of mosquitoes is six, that means that there are 6 chromosomes in every somatic (non-reproductive) cell,including the cells that make up the stomach.The six chromosomes represent two three-chromosome sets the mosquito received one set of three chromosomes from the egg cell of the mother and a similar set of three chromosomes from the sperm cell of the father.</span>
Elements are ionized because they aspire to be stable. The most stable form are the ones with full octet of electrons, the noble gases which consist of the last column in the periodic table. The rest of the elements either accept or readily donate electrons to conform to the electronic configuration that is the same with the nearest noble gas.
1. Potassium's nearest noble gas is Ar which is one electron fewer. So, when ionized, it donates 1 electron. Hence, K⁺.
2. The nearest noble gas for fluorine is Neon which is 1 electron more. Hence, it has to accept one more electron. Hence, F⁻.
