Hydrogen needs only 1 electron to complete its outer shell. the configuration of Hydrogen is 1s1 this indicates that it has only 1 electron in the shell S.and to complete the S shell H needs only one electron as the capacity of the S is 2.

How man electrons would you need to fill the outermost ring of hydrogen?

1: The outermost ring of hydrogen is the s-level, which can contain only two electrons, and a hydrogen atom itself already has one of these electrons.


Do all atoms want 8 electrons?

No, Hydrogen, Lithium and Beryllium tend to complete 2 electrons in outermost shell and most of the Transition metals tend to complete 18 electrons and other 8 electrons.


How many electrons would you need to fill the outermost ring of hydrogen?

The outermost ring of hydrogen, or the first energy level, can only hold a maximum of 2 electrons.


Atoms with lessthan 4 electrons in their outermost shell?

Hydrogen and Helium


How many electrons are in the outermost shell for hydrogen?

Only one electron exist.


What aspects of an atom determine how an atom will bond to another atom?

the outermost electrons of an atom. these are called valence electrons. atoms are also grouped in the periodic table based on their valence electrons. to complete a full outermost shell there must be 8 electrons. hydrogen has 1 valence electron. and oxygen has 7. they are able to bond together because of how many valence electrons they have.


Does H have seven electrons in their outermost level?

Hydrogen (H) has one valence electron.


Are all the electrons in atoms used in bonding?

No, except for hydrogen. Bonding uses outermost electrons (outside full shells).


Electrons are those found in the outermost energy level of an atom?

Electrons are those found in the outermost energy level of an atom?They are called valence electrons.


What is the octet rule in terms of lewis structures?

Octet rule states that each electron wants to complete its octet ( 8 electrons in the outermost shell) or a duplet (in case of hydrogen and helium).


How many electrons does hydrogen have on outermost shell?

One. In nature, however, hydrogen forms a diatomic bond making it found as H2.


Give an example of a covalent compound?

hydrogen molecule (H2) : is single covalent bond where each H atom shares with one electron to complete it's outermost shell (k level) with two electrons and becomes more stable.oxygen molecule (O2) : is a double covalent bond where each (O) atom shares with two electrons to complete its outermost shell (L level) with 8 electrons.nitrogen molecule:is a triple covalent bond where each atom shares with 3 electrons to complete its outermost shell (L level) with 8 electrons and become more stable.
