The element in period 2 with the most mass is Neon (Ne).
Magnesium
Oxygen is the period 2 element most likely to form an ion with a charge of minus 2 because it readily gains two electrons to achieve a stable electronic configuration.
The element phosphorous (P) is located in group 15, period 2.
what element is found between period 2 and group 14
The element in group 2 period 3 is magnesium (Mg).
Neon element in the periodic table period 2 has most mass.It has atomic mass of 20.17.It is colorless and odorless.
The element with the least mass in Period 2 is Lithium (Li). It has an atomic mass of approximately 6.94 g/mol
Boron
Short answer: boron. Long answer: any element with 11 protons or less could theoretically have an atomic mass of 11, as the mass = Number of Protons + Neutrons, if you add/take a certain number of neutrons from the atom it will be able to have an atomic mass of 11, but some aren't possible and others are too unstable, and will decay instantly.
fluorine
Magnesium
Fluorine is the most reactive nonmetal in period 2 of the periodic table.
lithium and fluorine
Oxygen is the period 2 element most likely to form an ion with a charge of minus 2 because it readily gains two electrons to achieve a stable electronic configuration.
Helium is a period 1 element.
The element in period 2 of the periodic table with an atomic mass of approximately 11 amu is boron (B). However, it's important to note that boron has an atomic mass of about 10.81 amu, which rounds to 11. Boron is a metalloid and is located in group 13 of the periodic table.
The element phosphorous (P) is located in group 15, period 2.
