Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.

What subscripts would you most likely use if an alkali metal and a halogen formed an ionic compound?

I would most likely use a +1 subscript for the alkali metal and a -1 subscript for the halogen in an ionic compound, as alkali metals typically form ions with a +1 charge and halogens typically form ions with a -1 charge.


Is iodine an alkali metal?

No, iodine is not an alkali metal. Iodine is classified as a halogen, a group of elements that are highly reactive nonmetals. Alkali metals are a separate group of elements that include lithium, sodium, and potassium.


Is phosphorus an alkali metal?

No, phosphorus is not an alkali metal. It is a nonmetal element that is found in the nitrogen group of the periodic table. Alkali metals are found in Group 1 of the periodic table and include elements such as lithium, sodium, and potassium.


Is fluorine an alkali?

NO!!!! Fluorine is an elemental gas in the HALOGEN Group. The word 'halogen' is from Latin and means 'salt maker'. So when fluorine is combined with a Group (I) or (II) metal (Alkali/Alkali Earth Metal) ot forms a salt. e.g. 2Na(s) + F^(2)(g) = 2NaF(s) ( The chemical salt).

K, potassium being a metal is highly reactive towards non metals.


What type of elements are in potassium fluoride?

Potassium fluoride only contains the elements potassium and fluorine. Potassium is an alkali metal. Fluorine is a halogen, which is a type of nonmetal.


What subscripts would most likely be used if an alkali metal and a nonmetal from group 6A formed an ionic compound?

The alkali metal would have a subscript of +1 while the nonmetal from group 6A would have a subscript of -2 to balance charges.


How do you know if an ionic compound between an alkali metal with a nonmetal is done correctly?

Since all alkali metals form a 1+ ion, the number of alkali metal atoms in the formula should be equal to the charge on the negative ion.
