How many electrons are unpaired in the outermost shell of aluminum (Al atomic number 13)?
Aluminum (Al), with an atomic number of 13, has the electron configuration of (1s^2 2s^2 2p^6 3s^2 3p^1). In its outermost shell (the third shell), aluminum has three electrons: two in the 3s subshell and one in the 3p subshell. Since the 3p subshell can hold up to six electrons and only has one electron, there is one unpaired electron in the outermost shell of aluminum.

What is the number of unpaired electrons in a strontium atom?
A strontium atom has the atomic number 38, which means it has 38 electrons. The electron configuration of strontium is [Kr] 5s², indicating that its outermost shell (the 5s subshell) is fully filled with 2 electrons. Since all the electrons in strontium are paired, it has zero unpaired electrons.
What are some paramagnets?
Some examples of paramagnetic materials include oxygen, aluminum, and titanium. These materials are weakly attracted to magnetic fields and have unpaired electrons in their atomic or molecular structures.

There are 3 electrons in the outermost shell of an aluminum atom, as it has atomic number 13.
How many unpaired electrons are in sulfur atom atomic number 16?
There are 2 unpaired electrons in a sulfur atom with atomic number 16. This is because sulfur has a total of 6 electron in its outermost shell, with 4 paired electrons and 2 unpaired electrons in its electron configuration.
What could be the proton number of an element that has three unpaired electrons in each of its atoms?
The proton number of an element is equal to its atomic number. If an element has three unpaired electrons in each of its atoms, it means that it has three unpaired electrons in its outermost shell, indicating that it belongs to group 13 of the periodic table. Therefore, the proton number of this element would be 13, which corresponds to the element aluminum.

A strontium atom has the atomic number 38, which means it has 38 electrons. The electron configuration of strontium is [Kr] 5s², indicating that its outermost shell (the 5s subshell) is fully filled with 2 electrons. Since all the electrons in strontium are paired, it has zero unpaired electrons.
How many electrons are found in the outermost shell of alumimum Al atomic number 13?
The atomic number of any element depends on the number of protons it has in its nucleus. Aluminium has 13 protons hence making the atomic number of aluminum 13.
How many electrons are found in the outermost shell of aliminum?
Aluminum has an atomic number of 13. Thus, neutral aluminum has 13 protons and 13 electrons. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p1. We can see that 3 is the outermost shell and that there are 3 electrons found there.
How many unpaired electrons are in a sulfur atom if the atomic number is 16?
There are 2 unpaired electrons in a sulfur atom with an atomic number of 16. Sulfur has 6 electrons in its outer shell, and 4 of them are used to form covalent bonds, leaving 2 unpaired electrons.
