From the periodic table:
the mass of lithium = <span>6.941 grams
Since lithium is monoatomic, therefore, the molar mass of lithium = </span><span>6.941 grams
Now, we need to calculate the mass of two moles of lithium:
mass of two moles of lithium = 2 * </span><span>6.941 = 13.882 grams
Based on the above calculations, the answer is:
True</span>

hope i help my bad if i'm wrong
Explanation:
water evaporates because when h2o (water) particles heat up, they gain energy causing them to start to vibrate. this moves the oarticles further and further away from eachother and making the substance less dense, and turning it into a gas. meaning it has evaporated
The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
