<h3>
Answer:</h3>
= 3.384 × 10^23 atoms
<h3>
Explanation:</h3>
We are given 18.016 g of sulfur
We are required to determine the number of atoms of sulfur
We will use the following steps;
<h3>Step 1: Determine the number of moles of sulfur </h3>
Number of moles = Mass ÷ molar mass
Molar mass of sulfur = 32.065 g/mol
Therefore;
Number of moles = 18.016 g÷ 32.065 g/mol
= 0.562 moles
<h3>Step 2: Determine the number of atoms </h3>
Using the Avogadro's constant;
1 mole of an element = 6.022 × 10^23 atoms
Therefore;
For 0.562 moles;
= 0.562 moles × 6.022 × 10^23 atoms
= 3.384 × 10^23 atoms
Therefore; there are 3.384 × 10^23 atoms in 18.016 g of Sulfur.
A neutral atom in its ground state contains 28 electrons. this element is considered a <span>transition </span>element, and has 8 electrons in orbitals with l = 2.
Electron configuration: ₂₈X 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁸ 4s².
l is azimuthal quantum number, l = 2 describes d orbital. There is eight electrons in 3d orbital.
