Answer:
Fluorine is identified as the most reactive nonmetal and the most electro-negative element in the periodic table, making it the strongest oxidizing agent. Caesium is the most reactive metal in the periodic table, so much that working with this metal often ends in explosions!
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
Hope that helps.
Nobel gas, it is in the last row of the periodic table and therefore is a noble gas
Answer:
Molar mass = 99 g/mol
Explanation:
Phosgene contains carbon, oxygen and chlorine atoms. Its molecular formular is; COCl2
The molar mass is given as the sum off the individual atomic mass of the elements in the compound.
Molar mass = C + O + 2Cl
Molar mass = 12 + 16 + 2(35.5)
Molar mass = 99 g/mol
Answer:
molecule. The smallest part of a compound is the molecule. A molecule retains all the properties of that compound.
