Actually aluminum is a little unstable. Its electronic configuration is 2,8,3. To be stable an element needs to have a full outer electron shell so to become stable Aluminium needs to lose 3 electrons to become 2,8 so it will have a full outer shell (8 electrons)
Aluminum, of course. Silicon is a metalloid while Aluminum is a metal.
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.
Because Aluminum comes before Silicon in the dictionary
Aluminum-silicon eutectic alloy can be made by melting aluminum and silicon at the eutectic composition (around 12% silicon) and allowing it to cool slowly to form a structure with alternating layers of aluminum and silicon. Controlling the cooling rate is crucial to achieve the desired eutectic microstructure and properties.
Elements get stable only when it completes electron octate in its outermost orbit. Elements make compounds with other elements to gain or reduce electrons to get stability. silicon make bonds with oxygen and make silicon dioxide to get stable.
Aluminum, of course. Silicon is a metalloid while Aluminum is a metal.
Silicon-based life is more likely than neon or aluminum-based life because silicon can form more complex molecules similar to carbon, making it more versatile for biological processes. Neon is a noble gas with limited chemical reactivity, while aluminum is less abundant and stable in common biological conditions.
Yes, carbon is a more stable element than silicon. Carbon forms stronger bonds due to its smaller atomic size, leading to greater stability in its compounds. Silicon, on the other hand, tends to form weaker bonds and is less stable compared to carbon.
Aluminum has 13 protons and 13 or 14 neutrons. Silicon has 14 protons, and 14 to 18 neutrons.
Aluminium is a metal, silicon is a metalloid.
Silicon, like carbon, has four valance electrons, and needs another four to have a stable octet.
In the periodic table of Mendeleev silicon is placed after aluminium.
The mantle has less aluminum and less silicon than the crust does.
Natural isotopes of silicon are: 28Si - 92,23 % (stable) 29Si - 4,67 % (stable) 30Si - 3,1% (stable) 31Si - traces (radioactive, unstable) 32Si - traces (radioactive, unstable)
