Why does sulfate have a 2 charge?
Sulfur has 6 valence electrons. Each oxygen atom has 6 valence electrons. Since sulfate has 4 oxygen atoms, that equals 24 valence electrons. Sulfate has a charge of 2− , which means it has an additional 2 electrons.
Is al2 so4 3 an ionic compound?
How many ions are present in aluminum sulfate?
It contain two ions which are Al3+ and SO42−.
Why does aluminum ion have +3 charge?
The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons. Aluminum then has three excess protons so the charge of a base aluminum ion is 3+. That’s the quick answer regarding how aluminum’s charge is 3+.

What is the charge of the sulfate anion of aluminum?
The sulfate anion has a −2 charge, whereas the aluminum cation has a +3 charge. The ionic compound must be electrically neutral. Thus we take 2 aluminum ions (6+ charge) and 3 sulfate ions (6-) charge, and achieve electrical neutrality. Are you happy with this treatment?
What is the charge of aluminium and bromine?
Aluminum has a +3 charge. Bromine has a -1 charge. When combined the ionic compound AlBr3 What is the chemical formula for aluminium and charge? Is aluminium sulfate an ionic compound? Is aluminum oxide ionic or molecular? Aluminum oxide is an ionic compound.
What is the charge of a base aluminum ion?
This is because the element’s atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons. Aluminum then has three excess protons so the charge of a base aluminum ion is 3+.
How many aluminum and sulfate ions are needed for electrical neutrality?
Thus we take 2 aluminum ions (6+ charge) and 3 sulfate ions (6-) charge, and achieve electrical neutrality. Are you happy with this treatment? What is the formula for sodium sulfate?
