MULTIPLE CHOICE QUESTION

When an electron is removed from Cesium,
what element does it LOOK LIKE?
Krypton
Xenon
Neon
Argon

Answer 1

B. Xenon

Step-by-step explanation:

On the periodic table, every element has an "atomic number". This number states how many electrons there are in an element.

Cesium's atomic number is 55, which indicates it has 55 electrons. 55 minus 1 is 54 electrons. The element that has 54 electrons is Xenon, whose atomic number is 54.
