Question

Consider these statements about an element E in Group 3A E is very difficult to reduce from its ore, due to its strong affinity for oxygen, and a practical method for doing so was only invented in the 1880s. Prior to that time, pure E was as expensive as gold Pure E is a light and strong metal, and forms a natural protective oxide coating on its surface that protects it from corrosion. It is used to make high-end cars and aircraft, and many consumer products for which its lightness and weather resistance, compared to steel, Justify its greater cost . E has the widest liquid temperature range of any element: it melts barely above room temperature but does not boil until over 2000 C In its standard state, E is a metal. Are all of these statements true about the same Group 3A element? o no If you said yes, what is E? Enter its chemical symbol:

Answer 1

Are all of these statements true about the same Group 3A element? No

Explanation

First, second and fourth statements are true in regards to aluminum (Al) which is a group 3A element but third statement is true only in regards to gallium (Ga) which is also a group 3A element.

Hence all the statements are not true about the same element
