What element is group 3 Period 3?
Group 3A (or IIIA) of the periodic table includes the metalloid boron (B), as well as the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl). Boron forms mostly covalent bonds, while the other elements in Group 3A form mostly ionic bonds….Group 3A.

What do all the atoms in period 3 have in common?
1 Answer. They all contain the same amount of electron shells.
What is special about Period 3 on the periodic table?
In the whole of period 3, the outer electrons are in 3-level orbitals. These are all the same sort of distances from the nucleus, and are screened by the same electrons in the first and second levels. The major difference is the increasing number of protons in the nucleus as you go from sodium across to argon.
What elements in period 3 are metals?
The third period contains eight elements: sodium (Na), magnesium (Mg), aluminium (Al), silicon (Si), phosphorus (P), sulfur (S), chlorine (Cl), and argon (Ar). Among these, three are metals (sodium, magnesium, aluminium), four are nonmetals (phosphorous, sulfur, chlorine, argon) and one is metalloid (silicon).
What is Group 3 on the periodic table?
Group IIIb, the main group, comprises boron, aluminium, gallium, indium, and thallium.
Which atom is most likely to form a 3+ ion?
A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−.
What is group 3 on the periodic table?
What element is in group 2 period 3 of the periodic table?
magnesium
Hence the name of the element is magnesium.
Why is chlorine in period 3?
It has the highest electron affinity and the third highest electronegativity of all the elements; thus chlorine is a strong oxidizing agent.
What element is in group 3 period 2?
Hence the name of the element is magnesium.
Which element forms an ion with charge 3+?
Knowing this lets us use the periodic table to identify the element as Al (aluminum). The Al atom has lost three electrons and thus has three more positive charges (13) than it has electrons (10). This is the aluminum cation, Al3+.
