How many electrons are allowed in the 3rd shell?
Does the third shell hold 8 or 18 electrons?
The third shell in its lowest state has room for 8 electrons but including the higher energy 3d electrons it has a capacity of 18 electrons.
How many electrons are in the outer shell of sulfur?
What does sulfur combine with?
It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements. Millions of tons of sulfur are produced each year, mostly for the manufacture of sulfuric acid, which is widely used in industry.
Is Sulfur positive or negative charge?
Sulfur is in group 6 of the periodic table. The charge is negative, since sulfur is a non-metal.
What is the most common charge of sulfur?
What is PB charge?
Group IV A (14) metals form cations with +4 charge, although tin (Sn) and lead (Pb) can form cations having +2 charge.
What is the charge of NB?
Compounds of niobium are of relatively minor importance. Those found in nature have the +5 oxidation state, but compounds of lower oxidation states (+2 to +4) have been prepared. Quadruply charged niobium, for example, in the form of the carbide, NbC, is used for making cemented carbides. electron config.
Can aluminum have multiple charges?
When an aluminum atom becomes an ion, it drops three electrons. Since there are only 10 electrons, their value is subtracted from the number of protons, and the difference is a positive three. Therefore, an ion of aluminum has a positive charge of three, shown as 3+.
Why does aluminum have a charge of 3+?
As Al has 3 valence electrons as M(3) so it tends to lose electrons then after losing these 3 electrons it has 10 electrons and 13 protons, and 10 electrons are neutralized by 10 protons out of 13, and the further excess 3 protons out of 13 appear as +3 charge.
What will be the charge on aluminum when it fulfills the octet rule?
+3 because all Group 13 ions will lose 3 electrons (this is easier than gaining 5 electrons!) to fulfill the Octet Rule. For example Aluminum’s ion possesses 13 protons and 10 electrons- it’s overall charge is +3.
Why does Aluminum lose 3 electrons?
It’s easier to lose 3 electrons than gain 5 electrons to fill the outer shell. Therefore aluminum atoms will lose 3 electrons so it takes on a +3 charge when it becomes ion. Specifically it would be a cation due to the positive charge.
How many energy levels are there in aluminum?
|Number of Energy Levels:||3|
|First Energy Level:||2|
|Second Energy Level:||8|
|Third Energy Level:||3|
