The element with a mass of 55 and 30 neutrons in its atoms is zinc (Zn). This can be determined by subtracting the number of neutrons from the atomic mass of the element.
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."
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.
At present (2013) the Periodic Table lists 118 elements in total. A small number of these are not naturally occuring and have only been synthesised under laboratory conditions and only in exceptionally minute quantities. Elements consist of particles called atoms that consist of protons, electrons and optionally neutrons. Protons and neutrons are in the core of the atom, while electrons reside on different energy levels in a cloud around the core. The atomic number of the element is determined by the number of protons in the core. The lightest, simplest element in the universe is hydrogen-1, which consists of one proton and one electron. There are also isotopes (different types) of hydrogen that have one or two neutrons in the core. Since the number of protons defines the element, we can create a different element by adding more protons to the core. To make the new element an atom, we need to add a corresponding number of electrons, since protons are positively and electrons are negatively charged and an atom is always neutrally charged. The more protons and neutrons you add to a core, the bigger it gets. When the core gets bigger, it also gets more unstable. This puts limits to what kind of elements occur in nature and also causes some elements to be radioactive. The number of different elements that are proven to exist is 118, with the largest atom being number 118 (temporary name ununoctium), since element number 119 is yet to be found. As of 2012, 55 hypothetical elements are being created.
Ceasium is a metal element. Atomic number of it is 55.
Barium (Ba)
Manganese is a metal element. Atomic mass number of it is 55.
Cesium has 55 protons, 78 neutrons, and 55 electrons.
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
The atom has 25 protons in its nucleus based on the atomic number. The atomic mass of 55 is the sum of protons and neutrons in the nucleus. Therefore, the atom has 30 neutrons (55 - 25 = 30).
Oh, dude, Molybdenum, like, totally rocks 42 protons, 54 neutrons, and 42 electrons. It's like the cool kid at the periodic table party, you know? Just hanging out with its atomic number 42, being all stable and stuff.
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."
The element with 54 protons is Xenon (Xe). However, the number of neutrons does not match the most common isotope of Xenon, which has 77 neutrons. The arrangement of 78 electrons suggests that this atom is ionized, with a +24 charge due to the excess number of protons.
This atom would be a specific isotope of cesium, with an atomic number of 55. Its mass number, which is the sum of protons and neutrons (55 + 76), would be 131.
The element that has 26 electrons 29 neuetrons and 26 protons is Iron (Fe) The number of protons= electrons/atomic number
there are 55 protons Cs in the periodic table .
Caesium is in the first raw. Atomic number of it is 55. So it has 55 protons.
