Which is more reactive cesium or francium?

Answer 1

francium it has loads more shells around it, making them easier to be displaced because the pull off the nucleus will be less as the magnetism between the electrons and necleus is sheilded better the more full shells there is between the nucleus and outer most shell

Answer 2

Francium is a group one metal it has only 1 electron in its outer shell. and for group 1 metals (also known as alkaline metals) it needs to loose this electron to have a full outer shell. Lithium has a total electron configueration of 2,1 and so its electron is closer to the nucleus having a greater force of attraction making if harder to loose this electron. as appose to francium which has 87 electrons making the force of attraction between them less making it easier to loose that spare electron

Answer 3

Francium is believed to be much more reactive than caesium because its electropositivity is greater and the electronegativity is lower. Francium is so reactive that you can't even get your hands on without government permission. If you put a gram of Francium in a bathtub of water in a bathroom, the bathroom will likely blow up.

Answer 4

Yes, Because as you know Flourine is in group7(Halogen) and Francium(Alkili metal) is in group1 So you probably confused because as you know the reactivity of a substance depends on the amount of electrons on its outer shell.And they both need to gain or lose one electron to gain a full outer shell.The Nucleus is positively charged and Flourine is in Period2 and so has only two shells so the force attracting the negatively charged electron is greater because the nucleus is close to the outer shell. Francium is in Period7 & so has seven shells so the Nucleus is futher away from the outer shell making it easier to loose the electron to gain a full outer shell. However what I'm saying that the energy it takes to gain a Electron is less because the Nucleus is positively charged you would need more shells (which would increase the range between the nucleus and its outer shell) in order to make a substance as reactive as Flourine and become Positive charged when it reacts(have to loose an electron when it reacts to gain a full outer shell).

This is just my theory I might be correct but I could also be wrong. ASK YOUR TEACHER!!!!!!!!!

Adding to that: generally speaking, everything above is correct, but it's not a practical question. Fluorine is a common element encountered in chemistry, but francium is not. It's extremely rare, and really only exists as a brief by-product of certain nuclear decay processes. It's half life is impractically short and at any moment the total amount of francium present in the earth's crust is 50 grams or less.

Answer 5

yes. its valence electrons are much further apart from its nucleus than that of Caesium. Therefore it loses its electron easier, IE is more reactive

Answer 6

Francium is considered the most reactive metal and fluorine the most reactive nonmetal.

Answer 7

Francium is considered as the most reactive metal; francium has the greatest electropositivity and the lowest electronegativity.

Answer 8

Francium is considered the most reactive metal.

Answer 9

Francium is more reactive than potassium.
