Which element in the periodic table period 2 has the most mass?
Neon element in the periodic table period 2 has most mass.It has atomic mass of 20.17.It is colorless and odorless.
What is the lightest elementt is period 2?
The lightest element that is in period number 2 is lithium. Lithium is also the solid that is the least dense.
What element in period 2 has a atomic mass of 11?
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.
If an element has a mass number of 4 and an atomic number of 2 how many neutrons does the element have?
2
