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.
Answer:
This is a simple case of ratios. (1 mol)/(22.4 L)=(n mol)/(.025 L) Then we cross multiply and we get 22.4n=.025 We divide each side by 22.4 to find n=.001116 mol Then to convert the moles to atoms we multiply, and cross-cancel the units (.001116 mol)/1 xx (6.02 xx 10^23 atms)/(1 mol) and we have 6.72 xx 10^20 atoms. I've found the trick of cross-cancelling units to be a very effective mnemonic, it always makes sure you carry out the correct calculation to find the desired units.

Answer:
Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus that holds genetic material as well as membrane-bound organelles.
