"These" should be referring to Alkali Metals.

They include metals such as Lithium, Sodium, Potassium etc.
They're classified as Group I elements because they all have one outmost shell electrons. This is why these metals are so reactive because they only need to lose one electron in order to achieve the octet of electrons (or duplet for Lithium), which means complete outmost shell electrons (2 or the 1st shell, others are 8). 

The reason why they're especially reactive to Halogens (Group VII) elements are that Halogens have 7 outmost shell electrons, which only needs one more electron in order to get to the octet of electrons. So, if an Alkali metal reacts with a Halogen, the metal would give one of their electrons to the Halogen, that way, both of the elements can have an octet of electrons (or duplet).

What should be done if you are planning to remove several components from a computer?
Usimov [2.4K]
If you plan to remove several components from the computer, it is best to save a back up files just so some files won't be lost and if you have ever corrupted your file. Another thing is to safely turn off your computer and have yourself provide pictures or to remember the cables that are placed in each switch before having to remove several components.
