Good afternoon My name is VANDITA YADAV and I am student of BYJUS 9th grade. My doubt is related with chemistry : We have to learn the periodic table or just need to understand it. In the first chapter of chemistry, the 2nd sub-chapter has table of cations where in the valency 4 - tetravalent elements, lead has the valency of 3+ instead of 4+. Is it an error or the lead has a valency of 3+ ? If yes then how?
