What else can I help you with?
What element has atoms with only one completely filled principal energy level?
undiscovered...yet, but there are a few...go forward 50 years and see
Which atom is more chemically reactive an atom with a partly filled energy level or an atom with all energy levels completely filled?
the one that is completely filled
Which atom has a completely filled 3rd principal enery level?
Nobel gases are said to have completely filled third principle energy level. One example is Argon which is a noble gas.
What are the electrons in the outermost energy level of an atom are called?
Completely filled octet.
Why helium does not form any chemical compound?
The external level of electrons is completely filled.
Element with a half-filled 5p level?
The element with a half-filled 5p level is antimony, which has the electron configuration [Kr] 4d^10 5s^2 5p^3. The half-filled 5p level stabilizes the atom, making antimony less likely to gain or lose electrons.
Element with half filled 5p level?
The element with a half-filled 5p level is antimony (Sb), which has an electron configuration of [Kr] 4d^10 5s^2 5p^3. It has five electrons in its 5p orbital, meaning it half fills the 5p level.
What is it called when an atom has an outer energy level is filled with electrons?
it is called complete or completely stable
What are the set of 8 electrons in an atom's outermost energy level called?
Completely filled octet.
What is an element with 7 valence electrons and 4 energy levels?
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
An element that is considered to be unreactive because it has a filled outer energy level is?
A noble gas is considered unreactive because it has a filled outer energy level. The full outer energy level provides stability and low reactivity, as the element does not need to gain or lose electrons to achieve a stable electron configuration.
Why isn't platinum reactive?
Because platinum is a noble metal: the external level of electrons is completely filled.
