More Properties of Metals
You have learned that elements in the sarne groùp of ,the periodic table have similar properties. For
example, the metals of Group 1 are so reactive they do'not exist uncombined in nature. The Group 2
metals are also quite reactive.
The tables below show the atomic radius and r,eactivity
of most of the metals in Groups 1 and
2.
The more reactive a metal is, the more stars appear in the reactivity column. You might'expect the
atomic radius of an element to be half its diameter. However, atoms do not have,a definite surface,
as a ball does. An atom's electrons are constantly moving around the nucleus in a region of space
that has no distinct edge. So, atomic radius is calculated as one half the distance between the nuclei
of two identical atoms. The unit of measurement is the,picometer (pm). One picometer is equal to
0.000000000001 meter.
