group 7A elements Spell out the number of electrons needed to complete the octet. Enter none if no electrons added. electron(s)group 6 A elements Spell out the number of electrons needed to complete the octet. Enter none if no electrons added. electron(s) Part C group 5A elements Spell out the number of electrons needed to complete the octet.

With our corresponding lesson by the name of Halogens (Group 7A Elements): Definition & Properties, you'll have a chance to learn even more about halogens. This video tutorial is going to cover ...

Enter the chemical formula of a binary molecular compound of hydrogen and a Group 7A element that can reasonably be expected to be less acidic in aqueous solution than HBr, e.g. have a smaller Ka. Question: Enter the chemical formula of a binary molecular compound of hydrogen and a Group 7A element that can reasonably be expected to be less ...
