Are you sure it's KR and not KP? If it is KP, it stands for karat plumb.
Xenon has 54 protons or 54 electrons. Its electronic configuration is Kr] 5s2 4d10 5p6 or 2, 8, 18, 18, 8
The orbital diagram for silver (Ag) is [Kr] 4d^10 5s^1. This means that the electron configuration of silver is [Kr] 4d^10 5s^1, indicating that silver has a completely filled 4d orbital and one electron in the 5s orbital.
"KR" inside a ring typically stands for "karat," indicating the purity of the metal used in the ring, such as gold. Karat is a unit of measurement used to describe the purity of gold in the alloy. For example, 24 karat gold is considered pure gold, while 14 karat gold contains 58.5% gold.
The atomic number of xenon is 54. It has 54 electrons and its electronic configuration is 2, 8, 18, 18, 8 or [Kr] 5s2 4d10 5p6
[Kr] 5s2 2, 8, 18, 8, 2
Natural isotopes of krypton are: Kr-78, Kr-80, Kr-81, Kr-82, Kr-83, Kr-84, Kr-86.
The element that has the same number of electrons as argon is Krypton (Kr). Both argon (Ar) and krypton (Kr) have 18 electrons in their neutral state.
Krypton (Kr) is the group 18 element in the ground state with a maximum of two completely filled energy shells.
On coins Kr means Kroner Denmark Greenland Norway There is also Kronor Sweden
Natural isotopes of krypton are: Kr-78, Kr-80, Kr-81, Kr-82, Kr-83, Kr-84, Kr-86.
