An element has an electron configuration of [Kr]5s1. Which of the following is TRUE about the element? Select ALL that are true. Click here of a copy of periodic table.
In a reaction, the elements tends to lose one electron to form a cation with a +1 charge.
The element is an alkali metal.
The element is Sr.
The element has one more electron than the previous noble gas
Homework Answers
The element with the electronic configuration [Kr]5s1 is Rubidium.
Rubidium tends to lose 1 electron to form an ion with +1 charge.
Rubidium is soft and silvery white in appearance. It is from the alkali metal group.
Krypton is a noble gas. So, it is true from the electronic configuration of Rubidium that it has one more electron in 5s orbital than Krypton.
So, options a,b and d are correct.
