What is the element that has a mass of 55 and contains 30 neutrons in its atoms?
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.
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
How many different elements do we know about?
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.
What is the atomic number for Cs?
ceasium is a metal element. Atomic number of it is 55.
Which element has 55 protons?
Barium (Ba)
How many protons neutrons and electrons are in cesium?
Cesium has 55 protons, 78 neutrons, and 55 electrons.
How many neutrons does Manganese-55 have?
Manganese is a metal element. Atomic mass number of it is 55.
How many protons neutrons and electrons does selenium-55 have?
Selenium-55 has 34 protons, 21 neutrons, and 34 electrons.
If an atom has a number of 25 and an atomic mass of 55?
It is an atom of the element manganese (symbol - Mn).
An atom with 55 protons and 76 neutrons?
An atom with 55 protons is a cesium atom. The mass number is the sum of the numbers of protons and neutrons, in this instance 131. Therefore, the atom is Cs-131.
What is the element 54 protons 54 neutrons and 78 electrons?
I think you meant "54 protons, 54 electrons, and 78 neutrons," because I don't think it's possible for any element to have such a high proton-electron different, especially when that element is the noble gas Xenon. Anyways, if you did make a typo, the element you're thinking of should be Xenon-134
What element has 26 electrons 29 neutrons and 26 protons?
The element that has 26 electrons 29 neuetrons and 26 protons is Iron (Fe) The number of protons= electrons/atomic number
How may protons does caesium have?
there are 55 protons Cs in the periodic table .
How many protons electrons and neutrons do Caesium have?
Caesium is in the first raw. Atomic number of it is 55. So it has 55 protons.
Mn is what on the periodic table?
55 - No. of protons and neutrons Manganese 25 - No. of protons
What is the element that has a mass of 55 and contains 30 neutrons in its atoms?
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.
