Question

An element X is in group 13 of the periodic table what is the formula of its oxide and chloride​

Answer 1

Answer:

xcl3andx2o3

Step-by-step explanation:

we know that group 3rd element should have it electron configuration as 2,3 or 2,8,3or 2,8,8,3and so on now we have conclude that the valency electrons are same so that element x has valency as 3

so this why it forms xcl3andx2o3

Answer 2

Element X of group 13 so the formula of its oxide and chloride is:---

◆oxide=X2O3 and chloride=XCl3

●Element belonging to group 13 has 3 electron in the outermost shell as we know that down the group the electronic configuration of elements in outermost shell remain same so the configuration of element of group 13 will be 2,8,3 or 2,8,8,3 or 2,8,8,18,3 and so on as we go down group but valency in all remain 3 as outermost shell has only 3 electron.So valency of element X is 3.

●Now hallide has valency of 1 as it is 1 electron short to complete its octect so by criss cross formula of hallide of group 13 is. MX3.

●Now oxide that is oxgen has valency of 2 as it is 2 electron short to complete its octect so by criss cross as valency of element in 13 group is 3 its oxide formula is. M2O3.
