carbon has to gain or lose 4 electrons to gain noble gas configuration.
Period Number: 4 Group Number: 18
Argon. "Period 3" means the third row of the periodic table. Noble gases are in "Group 18", the column on the far right.
Xenon is a noble gas. It belongs to group 18 and period 5.
Xenon is a noble gas, so it is in group 18. It is in period 5.
Kr Krypton
The noble gas, krypton
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.
Zirconium is in period 5. And the noble gas in this period is xenon
The element is germanium and the noble gas notation is [Ar]3d104s24p2
A noble gas. see www.education.jlab.org/qa/krypton.html
It is a noble gas, which are in group 18 (far right column of the periodic table). It is in period (row) 4. It is element 36. Its abbreviation is Kr.
Period 4, Group 18 is Krypton (Kr) and has 36 protons.
At the end of each period is a noble element. It is non-reactive.
Krypton is the elemnt present in group 18 aand period 4 with atomic number 36 and it is noble gas.
For helium it is 1s2. For the other noble gases it will be ns2 np6 where n is the period in which the noble gas in present.
This chemical element is the noble gas krypton (Kr).
