What level is filled by krypton?
The fourth electron shell is filled by krypton. Krypton is the last element in the fourth period on the periodic table. Each of the periods represents an electron shell. Elements in the first period have electrons in the first shell; elements in the second period have electrons in the second shell; and so on.
How many elements can the 3rd shell hold?
The 3rd shell can contain 18 electrons. The elements that have a 3rd shell as the outer shell are the the elements in period 3, where the 3s and 3p orbitals are filled to a maximum of 8 electrons. The 3d orbitals are filled in the 4th period in the transition elements.
elements in which the s and p arbitals in the outer shell are entirely filled are?
These elements, known as the alkali metals (group 1A) and alkaline earth metals (group 2A), are those in which the outer-shell s orbitals are being filled. On the right is a block of six columns. These are the elements in which the outermost p orbitals are being filled.
What does chlorine do when added to other elements?
I reacts in order to get a filled valence shell of electrons.
What elements had filled outermost shell?
I dont know the awnser to this ask someone eles
An atom that has 3 electrons in its second shell and a filled first shell will?
lose 3 electrons from its second shell
What is the name of elements whose outermost s and p sublevels are filled?
All the noble elements to the far right of the periodic table have their s and P sublevels in their valence shell filled, hence they are nonreactive.
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
How many electrons are in the valence shell of He?
There are two electrons in the valance shell of helium. Since this is the first shell, it is filled by two electrons.
What atoms need only 2 valence electrons to have a filled outer energy level?
There are two elements which can have a filled outer electron shell with only two electrons, those being the first two elements on the periodic table: hydrogen and helium. Their outer shell is the frist shell, principal quantum number 1. Also note that Hydrogen can also achieve a stable electron configuration with no electrons, in which case it consists of a single, naked proton.
When a compound is formed by two or more atoms of different elements joining the outer electron shell of the compound is completely filled with elecrons?
No. The valence shell of each atom in the compound is filled, each achieving a noble gas configuration.
Does krypton have a filled valence shell?
The outer shell is completely filled.
