Do metals gain electrons to have full octet?
No, metals tend to lose electrons to achieve a full octet.
How many electrons are needed to fill the outer shell of sodium?
Two electrons are needed to fill the outer shell of a sodium atom. The outer shell for sodium is the 3s sublevel. A neutral sodium atom has one electron in its 3s sublevel. Since atoms undergo chemical bonding in order to gain a noble gas electron configuration, called an octet, sodium atoms will lose their single 3s electron, becoming sodium atoms with a 1+ charge. By doing this, sodium ions become isoelectric with the noble gas neon, and achieve an octet, becoming stable.
When sodium reacts with chlorine does sodium gain or lose an electron?
Sodium only has one valence (outer shell) electron. It wants to fulfill the octet rule and have a full (8 valence electrons) outer shell. It could do this by adding 7 electrons to the one that's already there, or it could simply lose the one electron it has because the next shell is already full. But since it is "easier" for sodium to lose a single electron and requires the least amount of energy, this is what it does.
How could calcium achieve a stable octet?
Lose two electrons to form a doubly charged calcium cation.
Sodium and chloride atoms combine readily because they both tend to lose electrons?
This seems more like a statement of fact than a question. In any case, the statement is half true. Chlorine tends to take electrons, while Sodium tends to lose them. The reason (which is what I suspect you want to find out) is that the electron configurations for Sodium and Chlorine atoms are very unstable. (Sodium Chloride is a compound while Sodium and Chlorine are the elements that make up the compound. When referring to them separately, please use the correct terminology.) Sodium has a lone valence electron, sitting all alone in the outermost orbital of the atom. Atoms will generally try to achieve a "perfect octet", in which the atom in question has 8 valence electrons. It is much easier to lose one electron than it is to try and gain seven more, so Sodium is very prone to losing it's only valence electron. Chlorine has the opposite situation. It has seven valence electrons, just one valence electron short of a perfect octet. Since it is easier to gain one electron than it is to lose seven, it will often react with elements that have just one spare valence electron, such as Sodium.
How many electrons will each atom either gain or lose in order to satisfy the octet rule of Na?
Sodium would LOSE 1 electron to satisfy the octet rule.
Do metals gain electrons to have full octet?
No, metals tend to lose electrons to achieve a full octet.
When metals lose electrons what do they form?
Metals lose electrons and form cations to get a full octet.
Does sodium not lose or gain electrons?
Sodium lose electrons becoming a cation.
What does it do to complete the octet?
It is necessary to gain/lose electrons.
Does xenon gain or lose electrons to be a stable octet?
Neither. It has a stable octet in its ground state.
What do metallic atoms produce when they lose their valence electrons?
An octet
What states that atoms tend to gain lose or share electrons in order to achieve a full set of valence electrons typically?
The octet rule.
How many electrons would an atom of magnesium have to lose to have a stable octe?
It'll have to lose two to have a stable octet.
Why do atoms share gain or lose electrons?
Atoms gain, share, or lose electrons to try and become more stable. Atoms will gain, share, or lose electrons until they have a stable 8 valence electrons in their outer shell which is called an octet, which is stated in the octet rule. See the attached links for information on the octet rule.
How many valence electrons do alkali metals lose to obtain an octet?
they lose one electron
When sodium and chlorine combine what happens to the electrons?
Chlorine gains electrons and sodium lose electrons
