Well other than the fact that it needs to lose one (group 1) normally in an ionic compound (metal and non metal bonding), it would be different seeming how your teacher/tutor defines it.
One, because it is a group 1 metal.
It has a full outer shell of electrons
it needs six more electrons to have a full outer valence shell.
It has a full outer shell of electrons.
Sodium and Chlorine are chemically unstable due to the amount of electrons each has in the outer shells (also known as layers) of their atoms. Sodium has 11 electrons. First shell: 2 electrons Second shell: 8 electrons Third shell: 1 electron As the number of electrons in the last shell is not 8 and as the shell is not full Sodium is chemically unstable. Chlorine has 17 electrons. They are arranged like this: First shell: 2 electrons Second shell: 8 electrons Third shell: 7 electrons The number of electrons in the last shell is not 8, and the shell is not full, and thus, chlorine is chemically unstable. To give an example of a chemically stable element, Argon has 8 atoms in its last shell, which is why it is chemically stable and therefore does not react with any element.
Just one.
One, because it is a group 1 metal.
Bromine has 7 electrons in its outer shell and needs to gain one electron to have a full outer shell and become an ion. It will gain this electron from an atom that has one electron in its outer shell such as Lithium or Sodium.
No.
It has a full outer shell of electrons
neon is a nobel gas... the outer electron shell is full the sodium atom has only one electron in the outer shell which is very unstable the sodium atom want to fill up that outer shell with joined atoms so that it becomes full... that is why it ionizes so easily... it is grabbing electrons from other atoms easily
No. Xenon doesn't react, it's a noble gas (meaning it has a full outer shell of valence electrons).
it needs six more electrons to have a full outer valence shell.
Beryllium has 2 outer shell electrons. Its full electronic configuration is:- 1s2, 2s2

Yes it is . The outer argon is full becoz it has 18 electrons
