Question

what block and what period are associated with the element sulfur, s? the p block and the second period. the s block and the third period. the d block and the third period. the p block and the third period. question 2 1 pts find silver, ag, on the periodic table. what are the block and period associated with it? the d block and the fourth period. the d block and the fifth period. the p block and the fourth period. the d block and the third period. question 3 1 pts what is the subshell notation and the number of orbitals that can have the quantum numbers n = 5, ℓ = 2? 5 d; 5 5 s; 2 5 p; 7 5 d; 7

Explanation:

1. Sulfur (S) has an atomic number of 16. Its electron - configuration ends with $3s^{2}3p^{4}$. The outermost electrons are in the p - orbital, so it is in the p - block, and it has 3 electron - shells, placing it in the third period.
2. Silver (Ag) has an atomic number of 47. Its electron - configuration has the outermost electrons in the d - orbital ($4d^{10}5s^{1}$), so it is in the d - block, and it has 5 electron - shells, placing it in the fifth period.
3. When $n = 5$ and $\ell=2$, the subshell is the 5d subshell. The number of orbitals for a given $\ell$ value is $2\ell + 1$. For $\ell = 2$, $2\times2+1=5$.

Answer:

1. the p block and the third period.
2. the d block and the fifth period.
3. 5 d; 5
