What else can I help you with?
Witch of these is not a monatomic element F Kr Rn Ne?
Kr is not a monatomic element. Kr is the chemical symbol for Krypton, which is a noble gas and exists naturally as a diatomic molecule (Kr2) rather than as individual atoms.
Which element exists as monatomic molecules as stp?
The noble gases always exist in monatomic form: Helium, Neon, Argon, Krypton, Xenon, and Radon.
Write the shorthand electron configuration for rhodium?
Actually it's [Kr]5s1 4d8 Rhodium has an atypical configuration
Why were no ionic radii given for He Ne Ar Kr Xe and Rn?
No ionic radii are given for noble gases like He, Ne, Ar, Kr, Xe, and Rn because they typically do not form ions due to their stable electron configurations. These elements have complete outer electron shells, making them less likely to gain or lose electrons to form ions.
What element on the periodic table had complet outer shells give the name and symbol for each?
All of the elements in group 18 have complete outer shells, and are called the noble gases. They are helium, He, neon, Ne, argon, Ar, krypton, Kr, xenon, Xe, and radon, Rn.
Which noble gas has the highest boiling point?
helium has the least density, xenon has the highest.
What has full s and p orbitals in the highest occupied energy levels?
All of the Nobel gases do (He Ne Ar Kr Xe and Rn)
What is the boiling point of natural gas?
The boiling point of natural gas, which is primarily composed of methane, is approximately -162 degrees Celsius or -260 degrees Fahrenheit. This is the temperature at which natural gas changes from a liquid to a gas state.
Predict the order of increasing boiling points of the noble gases?
The boiling points of noble gases increase with increasing atomic number. Therefore, the order of increasing boiling points is helium < neon < argon < krypton < xenon < radon.
Melting and boiling point of radon?
Radon (Rn) Melting points: 202.0 K, −71.15 °C, −96.07 °F Boiling points: 211.3 K, −61.85 °C, −79.1 °F
What are gases that do not bond or have ion charges?
These are the noble gases: He, Ne, Ar, Kr, Xe, Rn.
What elemnet is a gas?
N O F Ne He Cl Ar Kr Xe Rn
Witch of these is not a monatomic element F Kr Rn Ne?
Kr is not a monatomic element. Kr is the chemical symbol for Krypton, which is a noble gas and exists naturally as a diatomic molecule (Kr2) rather than as individual atoms.
What does not exist as a diatomic molecule?
Noble gasses, from group 18: He Ne Ar Kr Xe Rn
Which ion is isoelectric with Rn?
Po --> Polonium (gains 2 electrons to complete octet rule) Ra --> Radium (loses 2 electrons to complete octet rule) Both end up with 86 electrons, the same amount that Rn (Radon) has.
What is the highest rank RGN or RN?
RN - Registered Nurse - is the higher of the two.
Atom where the outer shell surrounds the nucleus is full?
These are the noble gases, He, Ne, Ar, Kr, Xe, Rn
