To whomever gets this right i will give 68 points on the next question for them and the brainliest answer. NEED HELP!
Lithium's atomic number is 3. Fluorine's is 9. Explain how an atom of lithium and an atom of fluorine combine by ionic bonding.

The answer to your question is below

Explanation:

The information given is not important to determine if the bond is ionic.

An ionic bond is when a metal and a nonmetal combine or when the electronegativity of the elements is higher than 1.7.

In this example, lithium is a metal and fluorine is a nonmetal so they will form an ionic compound.

Lithium is in group lA so it has 1 electron in its outermost shell.

Fluorine is in group VIIA so it has 7 electrons in its outermost shell.

Lithium donates one electron to fluorine so they become stable.

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
