The electron structures of lithium and sodium are very similar, because each has a single valence electron in the s orbital. This is what makes them alkali metals. Because they have only a single valence electron, it requires relatively little energy to remove the electron to form a positive ion, and give the particle a stable outer shell. For this reason, alkali metals are highly reactive, and must be stored in oil to prevent them from reacting with water vapor in the air.

In the periodic table you will see that Lithium and Sodium are both in group 1. You will also notice that they both react with water. Sodium will cause a small bang and Lithium will just fizz. Group 1 I think means that they will have 7 (8 - 1) electrons in the outer shell and can therefore react with things in Group 7.

As both lithium and sodium are in group 1 of the Periodic Table, they both have got 1 electron in the outermost shell.

They both have 1 electron in the outer shell.They are both in Group I .
Lithium Li ..... 2,1
Sodium Na .... 2,8,1
Potassium K ... 2,8,8,1
The reactivity increases on going down the group.

Uptill 12 all T or F questions, mightbe having more T values. Later more answers might be F. For the multiple choice, maybe better to go with B most times. If there is no / negligible negative marking perhaps this method might even get more than 50 %

Li- has 2 electrons on the K shell and 1 valence electron on the L shell
Na- has 2el on K, shell 8el on L shell and 1 valence electron on the M shell
this means they both have 2 electrons on the K shell and they both have 1 valence electron (Li on L shell and Na on M shell)
some additional info
Li's configuration of electrons is [He]2s1
Na's -----------------I I -------------- [Ne]3s1

Lithium and sodium are both alcali metals, have one electrone on the last open shell and the shells before it are closed.
`he alkali metals are a series of elements comprising Group 1 (IUPAC style) of the periodic table: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr). (Note that hydrogen, although nominally also a member of Group 1, very rarely exhibits behaviour comparable to the alkali metals). The alkali metals provide one of the best examples of group trends in properties in the periodic table, with well characterized homologous behaviour down the group.
The alkali metals are all highly reactive and are rarely found in elemental form in nature. As a result, in the laboratory they are stored under mineral oil. They also tarnish easily and have low melting points and densities. Potassium and Rubidium are very weakly radioactive (harmless) due to the presence of long duration radioactive isotopes.
The alkali metals are silver-colored (caesium has a golden tinge), soft, low-density metals, which react readily with halogens to form ionic salts, and with water to form strongly alkaline (basic) hydroxides. These elements all have one electron in their outermost shell, so the energetically preferred state of achieving a filled electron shell is to lose one electron to form a singly charged positive ion.` wikipedia

They are similar because they both have the same valence electron. I think the valence electron is 1.

they both have only one electron on here their outer orbit (shell). this makes them very reactive
