valence shell
You just said it, electrons. The "shell" is just an energy level. It is called a shell because it surrounds the atom, but it is just the electrons. Since there is no way to determine the exact location of an electron, it is referred to as an "electron cloud."
Because it has 6 electrons in its outer shell, just like oxygen.
An atom is most stable and unreactive when it has eight electrons in its outer shell, a configuration known as the octet rule. This is because having a full outer shell typically leads to lower energy and greater stability. However, helium is an exception, as it is stable with just two electrons in its outer shell.
Just one.
I believe it's just the outer shell. It is where the outer electrons are contained.
A lithium atom has one electron on the outer shell. This is because there is 2 electrons maximum on the inner shell, so there is one left over for the outer shell. Hope you understand now xx
Each row of the periodic table gives you one full electron shell, then you start a new shell when you start a new row. In each group you have the same number of electrons in the outer shell, you just get more shells as you go down the table.
you cant its inposible just pay attention in class and u will find out.
A happy atom has a full outer electron shell, which makes it stable. When atoms bond with other atoms, they do so to achieve a full outer shell through sharing, gaining, or losing electrons. This bonding process allows atoms to become more stable and form molecules.
The most stable electron configuration for any atom is to have a complete outer shell. For the smallest atoms, that can be no electrons at all (for H+) since no shell is equivalent to a complete shell, or just two electrons in the outer shell, such as for a helium atom, but for most elements that means 8 electrons in the outer shell. We then have atoms which have five or more electrons in their outer shell and therefore need three or less to complete their shell, and they tend to gain electrons because it is easier to gain three than it is to lose five. Similarly, there are atoms with three or fewer electrons in their outer shell, and they tend to lose electrons because it is easier to lose three than it is to gain five. In the middle we have an atom such as carbon, with four electrons it its outer shell; it can gain or lose electrons with equal ease.
The number that tells you how many electrons an atom needs to gain or lose to complete a shell is called the oxidation number. It indicates the electron gain or loss required for an atom to achieve a full valence shell.
It looks just like a regular methane but with a chlorine atom in one of the positions. The outer shell of the chlorine is filled in because it is large.
