9,192,631,770 Hz and varies less than one tenth of 10 billion second and therefore very accurate and precise to keep time.
The atom of the isotope caesium 133; the definition of second in SI is based on this atom.
133 what? what are the units here? err.....i suppose its tht of Fluorine's......hey, if u find out if flourine's atomic radius is more thn tht of helium's, jus lemme know. thnq
Caesium is a metal element. Atomic mass of it is 133.

Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
A caesium clock is a highly accurate atomic clock that measures time based on the vibrations of caesium atoms. It is used as a standard for defining the SI unit of time, the second, and is crucial for applications that require precise timekeeping, such as GPS systems and scientific research.
An ammonia clock measures time based on the frequency of microwave radiation absorbed by ammonia molecules, while a caesium clock measures time based on the vibrations of caesium atoms. Caesium clocks are more accurate and stable compared to ammonia clocks, making them the standard for defining the international unit of time, the second.

It's a clock that is synced with a service that tells time based on the movement of an atom.
The frequency of the atom defines a second and used for international time.
The atom and its atomic resonance frequency standard.
The atomic radius, which is the distance from the center of the nucleus of one atom to the center of the adjacent atom divided by two, of francium is 260 pm. This is measured when two francium atoms are covalently bonded, therefore having a covalent radius of 260 pm.
AnswerAll digital clocks are perfectly accurate! A strontium atomic clock developed by scientists at the University of Colorado is supposedly more than twice as accurate as the cesium atomic clock (the old "most accurate") was.Atomic clocks are the most accurate clocks that are available to the general public. To date, the most accurate clock made is the so-called quantum logic clock, which is accurate to about one second in 3.7 billion years.
Cesium will have a larger atomic radius than magnesium. This is because atomic radius tends to increase down a group in the periodic table, and cesium is located below magnesium in the periodic table.
there are 55 protons Cs in the periodic table .
