How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
What do atoms want to have for their outer energy level?
When the outermost energy level is filled, the atom is stable. Nature always tries to achieve stability.
How many electrons are called are needed in the outer energy level of most atoms for the atom to be stable?
Eight electrons, called an octet, are needed by most atoms in order to be stable.
What charge do sodium form?
Sodium only has one electron in its outer energy level which it wants to lose in order to leave a stable octet of electrons in the level below. Loss of one electron causes a charge of plus 1 on the remaining ion.Magnesium has two electrons in its outer energy level, thus by losing these it takes on a charge of plus 2 and leaves a stable octet of electrons below in the next energy level.
How many electrons are in the second energy level of neon?
Neon is a noble gas, therefore it is stable meaning that its outer energy ring is full. It has 8 elections on its outer energy level. Check out the related link for a picture of a model of Neons atom.
How do atoms get stable outer energy level?
They share their valence electrons
What is a Adam when it's outer energy level is filled with electrons?
Stable.
Which group has a stable number of electrons in their outer most energy level?
All the noble gases Helium, Neon, Argon, Krypton, Xenon and Radon have a stable octet of electrons in their outer energy level.
A gas that has a stable number of electrons in the outer energy level?
Noble gas
How many electrons of the most stable have in there outer energy level?
The most stable atoms/ions have 8 electrons in their outermost shell.
How many electrons does an atom usually need in its outer energy level to be stable?
2.
How many electrons does a chemically stable atom have in its outer energy level?
8 electrons
How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
What is it called when an atom has an outer energy level is filled with electrons?
it is called complete or completely stable
Are the atom is chemically stable when its outer energy level contains all the electrons it can hold?
yes
What is the groups number for elements that have a stable number of electrons in their outer energy level?
Group 8
How many electrons does an atom need in its outer energy level to be stable?
Most atoms require eight electrons in the outer shell to be stable. The exception is atoms that are only filling the s1 orbital, which becomes stable with only two electrons.
