Caesium melts at 84 degrees Fahrenheit and at room temperature has about the consistency of toothpaste. I'm not sure if that's technically "malleable" or not; if you tried to take an actual malleus (hammer) to it it would probably splatter. At lower temperatures, when it's not about to melt, it would indeed be malleable.
The compound formed between sulfur and cesium is called cesium sulfide.
The cesium ion is called cesium ion or Cs+.
The correct name for the cesium ion is "cesium ion" or "Cs+ ion".
The element that fits this description is silver. Silver is part of Group 11 and is known for its shiny appearance, malleability, and excellent conductivity of heat and electricity. It has an atomic number higher than cesium and lower than radon.

The formula for Cesium Peroxide is: Cs2O2
When cesium and fluorine react, they form the ionic compound cesium fluoride (CsF).
The high reactivity of cesium comes from its tendency to give up the one electron in its outermost shell and become a cesium 1+ ion, which is more stable. In cesium chloride, the cesium is already in its stable ionic form.
