When we say a gamete is haploid, we are actually saying that the gamete needs another gamete to form a whole cell. Think of haploid mean "hal...

  • Waiting for answer Why does PbCl4 exist but PbIO4 doesn't?

    PbCl₄ exists because a Pb atom has four . The of Pb is [Xe] 6s²4f¹⁴5d¹⁰6p². The inner subshells are filled, so the are 6s²6p². The most common oxidation state of Pb is +2, formed by the loss of the 6p electrons. The less stable oxidation state of Pb is +4, formed by the loss of the 6p and the...
