Element Cs:
What is it's name?
What is its atomic number?
What is its atomic mass?
How many protons does it have?
How many electrons does a neutral Cs atom have?
How many neutrons does it have?
The element Cs is cesium.
Its atomic number is 55.
Its atomic mass is approximately 132.9 g/mol.
Cesium atom has 55 protons.
A neutral Cs atom has 55 electrons.
It has a total of 78 neutrons.
The element Cs refers to Cesium.
The atomic number of Cesium(Cs) is 55.
The atomic mass of Cesium(Cs) is approximately 132.91 amu (atomic mass units).
Cesium(Cs) has 55 protons.
A neutral Cs atom would have 55 electrons, as the number of electrons is equal to the number of protons in a neutral atom.
Cesium(Cs) typically has 78 neutrons, as the atomic mass (132.91 amu) minus the atomic number (55) gives the approximate number of neutrons.
To answer these questions, we need to refer to the periodic table of elements.
Step 1: Locate Cs on the periodic table.
Cs stands for Cesium, a chemical element with the symbol Cs.
Step 2: Identify the atomic number.
The atomic number represents the number of protons in the nucleus of an atom. For Cs, the atomic number is 55.
Step 3: Determine the atomic mass.
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. For Cs, the atomic mass is approximately 132.91 amu (atomic mass units).
Step 4: Calculate the number of protons and electrons.
Since Cs is a neutral atom, it has the same number of protons as electrons. Therefore, a neutral Cs atom has 55 protons and 55 electrons.
Step 5: Find the number of neutrons.
To find the number of neutrons, subtract the atomic number from the atomic mass.
Neutrons = Atomic mass - Atomic number
Neutrons in Cs = 132.91 amu - 55 = 77.91 neutrons.
So, to answer your questions:
- The name of element Cs is Cesium.
- Its atomic number is 55.
- Its atomic mass is approximately 132.91 amu.
- A neutral Cs atom has 55 protons and 55 electrons.
- Cs has approximately 77.91 neutrons.
