63% Answer Correctly

reactants

ions

isotopes

products
Solution

The atomic mass of an element listed in the Periodic Table represents the average mass of a single atom of that element and is measured in atomic mass units (amu). This number is an average as some elements have isotopes with atoms that vary in their number of neturons and, therefore, differ in weight.

4

Which of the following is not true about simple magnets?

62% Answer Correctly

all of these are untrue

opposite poles repel each other

same poles repel each other

opposite poles attract each other
Solution

Simple magnets have two poles, north and south, and opposite poles attract each other (N attracts S, S attracts N). Likewise, the same pole of two magnets repel (N repels N, S repels S). The Earth has a magnetic field and North and South Poles which enables the use of a magnetic compass to determine direction.
