The element used in highly accurate atomic clocks is cesium. It is radioactive and has a well-know half life. This element seems to work the best in this manner.
if you mean atomic number then the answer is cadmium.
Titanium is a metal element. Atomic number of it is 22.
Cobalt is an element, and is a transition metal with atomic number 27.
Spectral interference is more common in atomic emission spectroscopy due to overlapping spectral lines.
The element copper is designated by Cu, with an upper case C.
curium
Caesium would be my guess
One of the most metallic metals is cesium. It is named for its sky blue spectral lines. Cesium is used in atomic clocks.

sodium!!!
The chemical element of atomic number 53, a non-metallic element forming black crystals and a violet vapour.
if you mean atomic number then the answer is cadmium.
A palladium is a safeguard, or a metallic element with an atomic number of 46.
No, lead is not a mono-atomic element. Lead is a metallic element that typically forms chemical bonds with other elements, creating compounds.
