Guida verificata passo dopo passo1
Understand that the number of electrons in a shell is determined by the formula 2n², where n is the principal quantum number representing the shell number.
Identify that the problem is asking about the 6th shell, so n = 6.
Substitute n = 6 into the formula: 2 * (6)².
Calculate the expression inside the parentheses first: (6)² = 36.
Multiply the result by 2 to find the total number of electrons: 2 * 36.
