Kr is krypton, and it has 36 protons, 36 electrons
The number of Neutrons varies depending on the isotope, but it has 48 neutrons in its most common (56.99%) stable isotope.
Other less prevalent but stable isotopes have 42 (0.36%), 44 (2.29%), 46 (11.59%), 47 (11.50%), and 50 (17.28%) neutrons.
Other known unstable, i.e. radioactive isotopes, have 43, 45, and 49 neutrons. Since these are all radioactive they typically are only present in minute amounts and their concentration is highly variable.

Total valence electrons Kr + 6 (F) that is 8+6(7) = 50 We'll start bonding 6 F around Kr with single bonds and we'll be left with 38 electrons. Now out of these 38 electrons 36 will be put around each F in the form of 3 lone pairs and remaining two electrons will be put on central Kr as a lone pair along with 6 bond pairs. You're welcome
How many protons neutrons and electrons are in Kr W?
Krypton (Kr) has 36 protons, 36 electrons, and typically 48 neutrons, as its most abundant isotope is (^{84}\text{Kr}). Tungsten (W) has 74 protons, 74 electrons, and usually 110 neutrons, based on its most stable isotope (^{184}\text{W}). The number of neutrons can vary slightly depending on the isotope.
