The element in group 14, period 3 on the periodic table is classified as a
(1) metal (3) metalloid
(2) noble gas (4) nonmetal

Answer is (3) - metalloid

Elements in group 14 can be classified as non metals, metalloid and metals. Group 14 has C, Si, Ge, Sn and Pb as its elements. C is a non metal. Si and Ge are metalloids while Sn and Pb are metals. 

Metalloids are elements which share both non-metallic and metallic characteristics.

The element in group 14, period 3 on the periodic table is Si. Si is a semiconductor means Si can conduct electricity but not good as metals. Conducting electricity ia one of metallic property. 

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
