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.

How do you draw a Lewis dot structure of Kr?
As a noble gas, krypton has eight valence electrons. To draw the Lewis dot structure, write the symbol for krypton, Kr, and then place two dots on the top, bottom, and two sides, for a total of eight electrons.
How many unpaired electrons are in Tc?
Technetium has 43 protons and electrons.
What is the number of valence electrons for Sn?
Sn has 50 total electrons and is in the Group 4a elements on the periodic table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
Which element forms a 3 ion that has the electron configuration kr 4d 6?
[Kr]4d6 ion has 42 electrons. As it is a 3+ ion, the parent atom would have 45 electrons. This would make it Rhodium Rh.
How many moles of Kr are contained in 398 mg of Kr?
The mass of 1 mole of an element is its atomic weight on the periodic table in grams.1g = 1000mgThe mass of 1 mole of Kr = 83.80g KrConvert mg Kr to g Kr.398mg Kr x (1g/1000mg) = 0.398g KrConvert g Kr to mol Kr.0.398g Kr x (1mol Kr/83.80g Kr) = 4.75x10-3mol Kr
How many electrons are in a Kr atom?
36
How many protons and electrons does Kr atom have?
A Krypton atom has 36 protons and 36 electrons each.
How many electrons do Rb have?
Rubidium (Rb) has a +1 ion, will have the same electron configuration as krypton (Kr) because the +1 status means it has lost an electron. The configuration is written 1s22s22p63s23p64s23d104p6.
How do you draw a Lewis dot structure of Kr?
As a noble gas, krypton has eight valence electrons. To draw the Lewis dot structure, write the symbol for krypton, Kr, and then place two dots on the top, bottom, and two sides, for a total of eight electrons.
What is Lewis structure for xef6?
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 unpaired electrons are in Tc?
Technetium has 43 protons and electrons.
Which element has same electron as argon?
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.
How many electrons must Kr lose to attain a noble gas electron configuration?
Krypton is a noble gas and need not lose electrons. It is already stable.
How many valence electrons does ribidium have?
Rubidium is in group 1. The electron configuration is [Kr] 5s1. It has one valence electron.
What is the number of valence electrons for Sn?
Sn has 50 total electrons and is in the Group 4a elements on the periodic table. The nearest Noble Gas that is before Sn is Kr, which has 36 electrons. Therefore, the number of inner electrons (the same as Kr's electrons) is 36, outer electrons is 4 and valence is 4 as well (because its a Group 4a
If the number of electrons is 44 how many electrons can go into each orbit?
The neutral atom with 44 electrons is ruthenium (Ru).The electron configuration of ruthenium is: [Kr]4d75s1.The number of electrons in shells is: 2, 8, 18, 15, 1.
Which element forms a 3 ion that has the electron configuration kr 4d 6?
[Kr]4d6 ion has 42 electrons. As it is a 3+ ion, the parent atom would have 45 electrons. This would make it Rhodium Rh.
