With at least one of the words without the words where my words occur. Iron, nickel, and cobalt, found alongside one another on period 4, may be grouped together because they are all magnetic to some degree or another this is far from the only notable characteristic about such metals, but provides a convenient means of further dividing the transition metals into smaller sections.
