Alkali metals have one electron that is an unstable arrangement in the outer orbit so they tend to lose this electron. It becomes ions with a charge of+1. (Answer from page#111 in the Grade 9 Nelson Science Textbook)
Halogens have seven electrons in the outer orbit which gain one electron in order to have a stable arrangement of electrons. It becomes ions with a charge of-1. (Answer from page#112 in the Grade 9 Nelson Science Textbook)

What happens when you react an alkali metal with a metalloid?
They combine directly to form salts. E.g. lithium + fluorine -- > lithium fluoride if i am not mistaken..
When a acid reacts with an alkali what are the twp products are formed what are they?
acid+alkali=salt+water
What product is formed when alkali metals are heated with oxygen?
Improve Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water
Is a covalent bond normally formed when an alkali metal combines with a non-metal?
No, ionic bonds form between alkali metals and nonmetals.
What will the ratio of ions be in any compound formed from a group A metal and a group A nonmetal?
The ratio will be 1:1. When they react chemically with one another, the group 1A metals (the alkali metals) give up one electron, forming ions with a charge of 1+, and the group 7A (17) halogens gain the electron given up by the metal, forming ions with a 1- charge. When they react chemically with one another, they form a neutral ionic compound with a ratio of 1alkali metal:1halogen. Na+ + Cl- --> NaCl Li+ + Br- --> LiBr K+ + F- --> KF
What kind of chemical bond is formed by transfer of electrons between alkali halogens?
