This gas is krypton.
argon (atomic number 18) is the closest to calcium (atomic number 20)
Argon, one of the noble gases.Argon - which is a noble gas, has atomic number 18.Argon - which is a noble gas, has atomic number 18.
The noble gas Neon (Ne) has an atomic number of 10
Gallium's atomic number is 31 and has a positive 3 charge which means it has lost 3 electrons to form an ion Ga3+. it has 28 electrons Hope this helps
The element that has an atomic number of 36 is Krypton, a noble gas in period 4.

Argon, one of the noble gases.Argon - which is a noble gas, has atomic number 18.Argon - which is a noble gas, has atomic number 18.
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.
The noble gas Neon (Ne) has an atomic number of 10
Yes it is. Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
Gallium's atomic number is 31 and has a positive 3 charge which means it has lost 3 electrons to form an ion Ga3+. it has 28 electrons Hope this helps
krypton
The element that has an atomic number of 36 is Krypton, a noble gas in period 4.
118 will be its atomic number.

The atomic number of xenon is 54 whereas the atomic number of the next noble gas, radon, is 86. So the elements with atomic number 55 to 86 will contain Xenon while writing the noble gas configuration. rhenium(Re) <3
Noble gases with atomic numbers 2, 10, 18, 36, 54 and 86 are known. The next in the series will be element with atomic number 118.
