Use the equation C = εA/d
Where C = capacitance, A = area, d = distance between plates & ε = electrical permittivity of the medium between the plates
Answer: D
Explanation: Boron (B), Silicon (Si), Germanium (Ge), Arsenic (As), Antimony (Sb), Tellurium (Te) and, Astatine (At) are all metalloids
Because size of an atom INCREASES from top to bottom and DECREASES from left to right on the periodic table. If to elements are in the same period they can't increase in size based on the up or down trend. Instead, notice that Alkali Metals are LEFT of Alkaline Earth Metals. Therefore, the Alkali Metal will be larger than the Alkaline Earth Metals.
Answer:
Generally, we know that ionic compounds are formed by reaction of metals and non metals and non metals form a covalent or non ionic bonds.
<u>IONIC COMPOUDS</u>
- Iron and chlorine (FeCl2) , ( FeCl3)
- Chlorine and Lithium (LiCl)
- oxygen and calcium ( CaO)
- Potassium and Sulphur ( K2S)
<u>NON IONIC COMPOUNDS</u>
- Potassium and Calcium (covalent bond)
- Sulphur and Bromine (covalent bond)
Explanation:
(solid)ice, because the molecules are very close together ,so they can keep the shape.
