Transcript

we have a given got an s How many electrons does each of developing biological trace elements have in its outermost electrons. In the first one is my ignition. Magnesium has developed atomic number. So it’s electronic configuration as um one is to two is two and two p 6 And three is 2. So here Mag nation belongs to Group two of the product table. So this is a group and we have here this is block and this is period third period s blog. And to group So it has two electrons in outermost electrons. Here are two electrons, two electrons in its outermost shell. And next yes, partly we have given biological crisis element is cobalt, cobalt ss symbol is CEO. And it is um 27. Atomic number is electronic configuration is okay. One is to to S two two p 6, three is 2 uh and three P 64 S two and three D seven. So COBOL…
