Consider these statements about an element E in Group 4A: • The most important modern use of E is as an ultrapure semiconductor used to make microelectronic chips. • E has two main allotropes: a shiny silvery-white metal at room temperature, and a brittle gray powdery form at colder temperatures. • Although E is not a common element on the Earth's crust, deposits of the mineral EO₂ are widely found, and this ore can be reduced to E with moderate heating and charcoal. • Under standard conditions, E is a metal.
