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.
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 2 period least mass?

What is the molecular mass of myristic acid C14 H28 O2?
The molecular mass of myristic acid (C14H28O2) is calculated by adding the atomic masses of each element in its chemical formula. Carbon (C): 14 atoms x 12.01 amu = 168.14 amu Hydrogen (H): 28 atoms x 1.008 amu = 28.224 amu Oxygen (O): 2 atoms x 16.00 amu = 32.00 amu Therefore, the molecular mass of myristic acid is 228.364 amu.
What element is in group iii period 2?

An element has 2 naturally occuring isotopesIsotopes 1 has a mass of 106.905 amu and a relative abundance of 51.8 percent and Isotopes 2 has a mass of 108.904 amu and abundance of 48.2 percent Find th?
The average atomic mass can be calculated by multiplying the mass of each isotope by its relative abundance (as a decimal), then summing the results. For this element, the average atomic mass would be (0.518 * 106.905 amu) + (0.482 * 108.904 amu), which equals approximately 107.87 amu.
