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?
The symbol for an isotope of cesium with 82 neutrons would be Cs-138. This indicates that the isotope has 55 protons (the atomic number for cesium) and 82 neutrons, making the total atomic mass number 138.
What is caesium?
Caesium is a chemical element with the symbol Cs and atomic number 55. It is a soft, silvery-gold alkali metal that is highly reactive and easily ignites when exposed to air. Caesium is used in atomic clocks, in high-energy physics research, and in various industrial applications.
This element has an atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium (atomic number 32), as silicon has an atomic number of 14.
Which element is the largest Li K Cs?
Cs (Cesium) is the largest element among Li (Lithium), K (Potassium), and Cs (Cesium) due to having the highest atomic number and larger atomic radius.
Write the symbol of the ion with a 1 plus charge atomic number 55 and mass number 133?
The symbol of the ion with a +1 charge and atomic number 55 (cesium) and mass number 133 would be Cs-133+.
Is Cs a element or a compound?

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.
Which is the element having biggest atomic size?
May be Cesium(Cs)
