Due to the fact that we must find the weight in 300 years, we must find the weight of the element in 3 half-lives. In order to do this, we must divide the original number, 1 kilo, by 1/8 to find the quantity left. 1 kilo = 1000 grams, 1000 g / 1/8 = 125g. This means that the answer should be D.
I hope I've helped! :)
I know one I think, the nucleus
If all of the bonding electrons in a molecule are bonded in two-hybrid sp orbitals are likely to have a linear shape.
<h3>What are sp orbitals?</h3>
One of a set of hybrid orbitals is produced when one s orbital and one p orbital is combined mathematically to form two new equivalent, perpendicular orbitals.
A linear molecule is one in which the atoms are arranged in a straight line (less than a 180° angle). The sp hybridization occurs at the central atom of molecules with linear electron-pair geometries.
Carbon dioxide (O=C=O) and beryllium hydride are examples of linear electron pairs and molecular geometry.
Hence, option A is correct.
