How many electrons does group 6A need to gain to become a noble gas?
They should gain 2 electrons to attain noble gas electronic configuration. (it doesn't become a noble gas as the number of protons are not same)
How many electrons does carbon have to give up to achieve a noble gas configuration?
4 but it will need energy, so carbon gain 4 electrons to achieve a noble gas configuration.
How many electrons does lithium need to add to satisfy the Octet Rule?
Seven electrons should be added to attain the higher noble gas configuration.
How many electrons do you need to become a noble gas?
A species (element, cation or anion) should have eight valence electrons to have a noble gas electronic configuration. However element upto atomic number 4 may have 2 valence electrons and attain the electronic configuration of helium noble gas.
How many electrons does silicon need to gain a noble electron gas configuration?
An atom of silicon needs to gain 4 electrons in its 3p sublevel to attain the noble gas electron configuration of argon, the noble gas in period 3 of the periodic table.
How many electrons would an atom of carbon need to have to be a negative ion?
There are six electrons in two shells.In order to stable carbon, it take electrons from nearest noble gas to stable the carbon.It order to stable carbon it gain -4 electrons from the nearest noble gas Neon.
