Aluminum has 13 electrons. Use aufbau principle or periodic table to put these electrons into orbitals. 1s2 2s2 2p6 3s2 3p1 Because there is a lone electron in the p orbital that is not paired, aluminum in its ground state has 1 unpaired electron.
I think you mean horse, and that would be Silver.
The lone pair pushes bonding electron pairs away.
since all the alkali metals have one electron in there outer most shell so there valency is always one & they are the most electropositive elements in the periodic table.they loose one electron from there outermost shell to form one positive charged cations.
The lone pair pushes bonding electron pairs away.
Atoms with 1 valence electron are typically found in Group 1 of the periodic table, known as the alkali metals. Examples include lithium, sodium, and potassium, all of which have one valence electron in their outermost energy level. This lone valence electron makes these elements highly reactive.
Cn- is paramagnetic. Cn is found in the Periodic Table and is known as Copernicium. A compound that is paramagnetic is one that will have a lone electron and Cn qualifies.
The Alkali Metals, which are the elements in Group 1 of the periodic table, each have one lone electron in their valence shell. And each of these elements wants to get rid of that single electron. These metals, which include lithium, sodium, potassium, rubidium, caesium and francium, are the most likely to lose electrons.
Simply for convenience. Were it included in the rest of the table those elements would fit between the transition ans alkaline-earth metals, and make the table too wide to be easily displayed on most pages.:-))))
to calculate the formal charge:Take the number of valence electron the neutral atom would have (found on the periodic table) and subtract it from the number of electrons in lone pairs +1/2 of the number of electrons in bonds
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
There are two lone pairs of electrons on the sulfur atom in the sulfite ion. This is because sulfur is in group 16 of the periodic table and has six valence electrons, two of which form a double bond with one of the oxygen atoms in the sulfite ion.
The answer is 1. This is because the only atom with lone paires is phosphorus and it only has 1.

There are 2 lone electron pairs in the NO2 ion. The nitrogen atom has one lone pair, and each oxygen atom has one lone pair, totaling to 2 lone pairs.
