The mass numbers of the different isotopes of that element are averaged according to their respective abundances in nature.
Explanation:
X = Group 1 metal
Y = Group 7 Non metal
The dots basically signifies the group.
Metal loses electrons and non metal gains electron. The valency of X is 1 and that of Y is 7.
X atom loses one electron and Y atom gains one electron.
The bond that forms between a metal and a non metal is an ionic bond.
The molar mass of glucose is 180.16g/mol. So to convert grams of glucose into moles of glucose, divided the mass in grams by the molar mass, and grams will cancel out leaving you with moles. 120g / 180.16 g/mol = 0.666 moles
Answer:
Red light bends the least. While Violet light bends the most.
