1. What element is a metalloid in group 3? 2. What group 1 element is a NON metal?
3.what period 3 element has 8 valence electrons

1.The metalloids; boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and astatine (At) are the elements found along the step like line between metals and non-metals of the periodic table.

2.hydrogen

The elements generally classified as nonmetals include one element in group 1 (hydrogen);

3.element iron

The element iron is in group 8, and therefore has two or three apparent valence electrons.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

what is the question here. i think you messed up.
