yes it would bond ccovalently
Aluminum would be more like sulfur as they are both nonmetals. Thallium, on the other hand, is a metal.
You would get a mixture.
As cations, they retain their original names (examples: aluminum chloride, sulfur dioxide). As anions, they get "ide" endings and become aluminide (very rare) and sulfide (not quite as rare). Combined with oxygen in complex anions, they form aluminates, sulfites, sulfates, etc.
To covalently bond aluminum and sulfur, you would need to have aluminum sulfide (Al2S3) formed through a chemical reaction. This can be achieved by heating a mixture of aluminum powder and sulfur in a controlled environment to allow the formation of covalent bonds between aluminum and sulfur atoms.
Aluminum forms a cation of +3 charge. Sulfite is an anion of -2 charge. To combine, the two would forum aluminum sulfite of the form Al2(SO3)3.
When lithium and sulfur combine, they do so as Li2S (lithium sulfide). This is an ionic compound.
For aluminum sulfide (Al2S3), the ratio of aluminum to sulfur atoms is 2:3. This means that for every 3 atoms of sulfur, 2 atoms of aluminum will react. So, to produce aluminum sulfide from 1.33 x 10^24 atoms of sulfur, you would need (2/3) * 1.33 x 10^24 atoms of aluminum, which is approximately 8.87 x 10^23 atoms of aluminum.
In a chemical reaction between lithium (Li) and sulfur (S), it is likely that lithium would donate its electron to sulfur, forming an ionic bond between Li+ and S2-. This creates lithium sulfide (Li2S), an ionic compound.
"Sulfur aluminide" is an incorrect name because it does not follow the naming convention for ionic compounds. The correct name for the compound formed between sulfur and aluminum would be "aluminum sulfide" as sulfur takes on a -2 charge in the compound.
Sodium > Aluminum > Chlorine > Sulfur. Atomic size generally increases as you move down a group on the periodic table and decreases as you move across a period from left to right. Sodium is in the same period as chlorine but is a metal, so it has a larger atomic size. Aluminum is in the same period as sulfur but is a metal, so it has a larger atomic size. Chlorine is a non-metal and smaller than both aluminum and sodium. Sulfur is a non-metal and the smallest among the four elements listed.
Aluminum sulfate has the chemical formula Al2(SO4)3, so the elements present would be aluminum (Al), sulfur (S) and oxygen (O).
Helium is chemically inert and does not combine with any other element (including thallium).
