Why do electrons want a full outer shell?
Atoms want a full outer shell because it completes all the gaps in the outside. With no gaps, other electrons don’t want to fit into those spaces. For example, a noble gas like Neon has a full outer shell. It doesn’t react with other chemicals because the electrons from other chemicals can’t fall in anywhere.
What does it mean to have a full outer shell?
When a shell completes its duplet or octet, it becomes complete or we can say attain a full outermost shell. As helium has only two electrons. So, they remain only in first shell which requires only two electrons to be completed. So, helium’s outermost shell is considered complete.
Why is a full outer shell more stable?
A full outer shell makes atom stable because the next in the series of energy subshells exists beyond the periphery of that which defines an atom. In other words; these are neutral atoms, so there is no positive or negative electric charge beyond the last shell.
Why are full electron shells more stable?
The properties of an element are determined by its outermost electrons, or those in the highest energy orbital. Atoms that do not have full outer shells will tend to gain or lose electrons, resulting in a full outer shell and, therefore, stability.
How many electrons does chlorine need to gain to have a full outer shell?
seven electrons

Is iron not from Earth?
Iron is also the fourth most common element in Earth’s crust by weight and much of Earth’s core is thought to be composed of iron. Besides being commonly found on Earth, it is abundant in the sun and stars, according to the Los Alamos National Laboratory.
Which metal is not from Earth?
But when we look at the full gamut of elements in the periodic table, there’s one missing that you might have expected to be there: the 43rd one, Technetium, a shiny, gray metal as dense as lead with a melting point of over 3,000 °F, that simply doesn’t occur naturally on our world.
Can iron be created on Earth?
All iron on Earth was produced by large stars that existed before our Sun formed: the iron was created during nuclear fusion and later released when the parent star(s) exploded, presumably supernova.
