How many electrons does bromine need to fill its valence shell?
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
What is the valance of electrons in carbon?
The atomic number of carbon is 6. 6 protons, 6 electrons. Two in the first shell and 4 on the second shell leaving 4 spaces open, making the second shell the valence shell and the 4 spaces open the valence- valence is the bonding capacity, in other words the electrons needed to fill the second shell. First shell max is 2 electrons Seccond shell max is 8 electrons
Which familt has atoms that gain 3 valence electrons to fill their outer shell?
Group 15
How many valence electrons are needed to achieve a full outer shell?
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
When is the valence shell stable?
Whenever the outside shell of the atom, or valence shell, is completely full with electrons. Ex: The noble gases are lucky enough to start out stable because they fill their outer shells.
How many electrons in hydrogen valence shell will give it a noble gas configuration?
Two electrons will fill a hydrogen's outer, or valence, shell.
How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
How many electrons are needed to fill carbon outer shell?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many electrons does bromine need to fill its valence shell?
Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
How many valence electrons will beryllium gain or lose to fill its outer shell?
Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
How many valence electrons will barium gain or lose to fill its outer shell?
It will lose 2 electrons.
How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
