What else can I help you with?
How many electrons are in the outermost shell of helium?
only 2 electrons.
How many electrons are found in the outer lever of all the noble gases except helium?
There are 8 electrons in the outer level of all the noble gases except helium. This full outer level gives them stability and makes them less reactive. Helium, as a noble gas, has only 2 electrons in its outer level.
Which is the noble gases does not posses 8 electronS in its outermost shell?
it is Helium.
Atoms with lessthan 4 electrons in their outermost shell?
Hydrogen and Helium
What are the features of outermost shell of noble gas?
They have 8 valence electrons (except for helium which has 2 valence electrons).
Where are valence electrons found in an atom?
Outermost shell
How many electrons does a sulfur have in its outermost shell?
Sulphur has 6 electrons in its outermost shell.
How many electrons are found on the third shell of helium?
the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
What valence electrons?
The electrons found in the outermost shell (or energy level) are known as the valence electrons.
What is duplet state?
A duplet state is when an element has two electrons in it's outermost shell For example-Helium
What do atoms in the same period have?
Their outermost electrons are in the same shell. For example, Helium and Hydrogen have 1 and 2 electrons respectively, and these electrons exist within the first electron shell. Lithium has 3 electrons and the third of these electrons is in the second electron shell, and so, it is a member of the 2nd period of the periodic table.
How many electrons does nitrogen have in its out most shell?
It has 5 electrons in its outermost shell.
