What is a non example of atomic mass?
The weight of a football is a non-example of atomic mass. Atomic mass refers to the average mass of an atom of a chemical element, while the weight of a football is a measure of the force of gravity acting on the football due to its mass.
How do the metallic properties of the elements change as you move from left to right on the periodic table?
Metallic character decreases as we move across a period. The electronegative character increases as we move across a period. So the element across the period will be non mettalic in nature.
What is the atomic mass mass in nitrogen?
Nitrogen is a non meta element. Atomic mass of it is 14.
What element has an atomic mass of 12?
The element that has the atomic mass of 12 is carbon. For elements the correct expression is atomic weight (not mass). The atomic weight of carbon (after IUPAC 2009) is [12,0096; 12,0116] or as a more simple, conventional value 12,011.
