Element T has an oxidation number of -2 (it needs 2 more electrons to become stable). Element U has a larger atomic radius than element Q. Element U does not follow the periodic trends like the other group A elements do. Element M is more electronegative than element O. Element Y is the most metallic element on this chart.

Based on this table, what is the relationship between density and atomic number? Element X has two natural isotopes. The isotope with a mass of 32 amu (32X) has a relative abundance of 29.91%. The isotope with a mass of 33 amu (33X) has a relative abundance of 70.09%. Calculate the atomic mass of this element. An element has three known isotopes.

The Atomic Mass of Metallo - Alternate. You may have noticed on the periodic table that the atomic mass of an element is usually not a whole number. That happens because of isotopes. An atom that is missing a neutron or has an extra neutron is called an isotope. They are still the same element; however, they are just a little different from ...

The atomic mass of an element is a weighted average of the mass of the isotopes of the element. Atomic mass is measured in atomic mass units (amu), which is based on the mass of a carbon-12 atom. The atomic mass of an element usually is close to the mass of its most abundant isotope. 50 Name Class Date
