How many protons would be present in an atom of barium?
There are four protons. Also four neutrons and four electrons
What is Ba atomic number?
Atomic Number is 47; Atomic Mass is 137.3; Element Name is Barium; Classified as the Alkaline Earth Metals.
What information can you gather knowing the atomic number and mass of an element?
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
What is the number of protons of helium?
Helium is number 2 on the Periodic Table, and the number of its mass is 4. So, therefore it has 2 protons, 2 neutrons, and 2 electrons !
Why atomic radius of barium is less than atomic radius of caesium?
Both cesium and barium have their outermost electrons in the 6s sublevel, Cs with 1 and Ba with 2, but barium has one more proton in the nucleus than does cesium, and this produces a greater effective nuclear charge and more attraction for the outermost electrons. This in turn pulls the two electrons in the 6s sublevel of barium slightly closer to the nucleus compared to the one 6s electron in cesium.
How do you determine the number of protons in a nuclide?
The number of protons in a nuclide is the atomic number for that element on the periodic table.
Which element has 56 protons in its nucleus?
Barium. Atomic number 56 The reason for this is because Barium has 56 protons and the protons determin the atomic number (56).Also, that would be the same number of electrons. I hope this helped you :]
Can you always determine an element by the number of protons?
Yes because the number on top of the box on the periodic table refers to the number of protons.
Can you determine the element with only knowing the number of protons?
The number of protons is the "atomic number", so you look that up in the periodic table.
Which element on the periodic table has 54 electrons?
Elements on the periodic table are arranged according to the number of protons in their nucleus, also known as their atomic number.54th element on the periodic table is Xenon.
How many protons would be present in an atom of barium?
There are four protons. Also four neutrons and four electrons
What role does atonmic number play in the periodic table?
The atomic number is the amount of protons in an element. The number of protons completely determine what element an atom is.
Can you determine the number of protons?
Yes. The number of protons is determined by the element's atomic number on the periodic table of elements. (Example: Nitrogen's atomic number is 7 therefore it has 7 protons.)
What number do the protons determine?
The atomic number (Displayed on the bottom left of the elements symbol on the periodic table)
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
What is the 56element of periodic table?
Barium, on the periodic table, has an atomic number of 56. Ba is the symbol for barium.
How do you Determine the number of protons in an atom of barium?
you must regret the day you left me. Without me, your pimpin' ain't the same without me.
