What difference did the wechsler tests have from other earlier intelligence tests?

-involves their factors and subtests

-Quantitative Reasoning: the ability to solve numerical problems

-Visual-Spatial Processing: the ability to analyze visually presented information, including relationships between objects, spatial orientation, assembling pieces to make a whole, and detecting visual patterns

-working memory: the ability to hold and transform information in short-term memory

-each of these 10 areas is assessed by one to three specific types of items           .

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
