in this problem, we are going to calculate, and I d required to remove an electron from how to get down at ST. See, according to your story, the energy off in the town in an orbit can be calculated is e. And that is equal to minus 13 by it. Six Electron world Indu These appear upon and secure here. These number up with guns inside the nucleus off in a dome on any speed spell. Quantum number. So hear me hell de equal to one fight. Hard to get him. And we have hard. Regina. Don't mean stirred three. So we have Andi call toe two. No, By putting the end and in the blood relation, we have a extent to you. Physical too minus 13. Quiet six. A letter on world into one Scared upon Theresa girl. So we hear e three equal to minus one point five 11 a let down What, in addition, means removal off another town from a particular our bitch. Therefore, to our nice telegram from a given state, an amount of energy has to be given which is equal to energy courses to buy data. Tron in the particular city dear. Full do iron eyes down from stead She we had to supply right and as equal to 1.511 little worked.
