Which element is the least reactive in period 4?
Noble gasses are least reactive of all the elements. So the least reactive element in the period 4 is Krypton. It is a noble gas with an atomic number of 36.
Which of the following are considered noble gases?
Helium, Neon, Argon and if another Krypton.
Is krypton and neon the same thing?
Yes. Both are noble gases, and are chemically almost indistinguishable without precise testing.
What has the largest ionization energy in period 4?
The noble gas, krypton
What is the basis for the organization of the modern periodic table is?
The modern periodic table does a lot of things. It organizes elements in order of electron orbitals for one thing (1s, 2s, 2p, 3s, 3p, 4s, ect..). It also has all noble gases stacked on top of each other helping to determine the columns of 1-8 valence electrons. It seperates all metals from nonmetals and elements in the same column will have similar physical and chemical properties.
Which element in period 5 of the periodic table has the greatest number of protons?
This element is the noble gas xenon (Xe) with 54 protons.
What is the group and period number of helium?
noble gases atomic number 2 chemical symbol He
What is the element symbol for the noble gas in the second period?
the element is neon and the symbol is Ne.
What is the chemical symbol a noble gas in Period 1?
He, helium
What is the number of protons in one atom of krypton?
Krypton is a noble gas. Atomic number of it is 36. It has 36 protons.
What element is a noble gas in period 6?
The element Radon (atomic symbol Rn) is the noble gas found in Period 6 of the periodic table.
What does the symbol Ne mean?
Neon Ne is the chemical symbol for neon, a noble gass.
Which atom has ten protons and ten electrons?
The noble gas neon has ten protons and an equal number of electrons.
How many protons are in krypton-80?
Krypton is a noble gas. It's atomic number is 36.We also know that the atomic number of an element is equal to number of protons present in its nucleus.Therefore the number of protons in krypton is 36.Make one thing clear in your mind that there is no kryton-80 because it is a noble gas, therfore it doesnt have any isotope.
Find the name of the element that has 36 protons in the periodic table?
36 protons = atomic number 36 = noble gas Krypton Kr
Does an ion have the same properties as its corresponding noble gas?
No, as the number of protons and neutrons in each will be different.
How many electron shells do noble gases have?
The number of electron shells depends on the noble gas. The number of shells will be equal to the period in which the noble gas is present.
