How many protons and neutrons does cesium 134 have?
Oh, dude, cesium-134 has 55 protons and around 79 neutrons. It's like the cool kid at the periodic table party, just hanging out with its atomic number of 55 and atomic mass of around 134. So, yeah, it's got its protons and neutrons chillin' like, "What's up, we're cesium-134."
What is the symbol of an isotope of cesium whose atoms have 82 neutrons?
You are looking for the symbol of cesium (Cs) and indication of its mass number. The mass number is the sum of the protons and neutrons. So if every atom of cesium has 55 protons, then the mass number of this isotope is 137. The mass number is indicated in superscript before the symbol: 137Cs
What is caesium?
Most likely Ceasium is a common misspelling of the name for the 55th element: Caesium or Cesium, symbol Cs.(The misspelling can be understood when written phonetically after the correct pronounciation: "see-zee-əm" . It should not be pronounced as "kee-zee-əm" as would be expected from -the correct- spelling 'CAE...')

How many protons neutrons electrons does Cs have?
Cesium (Cs) has 55 protons, as indicated by its atomic number. In a neutral atom, it also has 55 electrons. The number of neutrons can be determined by subtracting the atomic number from the atomic mass; the most common isotope of cesium has approximately 78 neutrons (55 protons + 78 neutrons = 133 atomic mass).
What element has the atomic mass of 56?
The element with an atomic number of 51 is Sb - Antimony; atomic weight = 121.75.
What element is Cs?
Cs is the chemical symbol for the element Cesium. Cesium is a soft, silvery-gold alkali metal with atomic number 55. It is used in atomic clocks, as a catalyst in organic synthesis, and in some medical applications.

Why is Cs more electropositive than Rb?
Cs is more electropositive than Rb because Cs has a larger atomic size and a single electron in the outermost shell, which makes it easier for Cs to lose an electron and form a cation. As we move down the group in the periodic table, atomic size increases, shielding effect increases, and atomic number increases, all of which contribute to the increase in electropositive character.
