I believe Neon is closest to Magnesium on the Periodic Table of elements.
Sorry if I'm wrong, hope I could help though! :)
Explanation: Sodium is a metal with a low electronegativity it will form an ionic bond with a non metal with a high electronegativity.
Both Florine and Sulfur are non metals with high electronegativity.
Neon is a noble gas family VIII A and normally doesn't form any bonds at all.

Answer: 1.99 x 10²² molecules H2
Explanation:First we will solve for the moles of H2 using Ideal gas law PV= nRT then derive for moles ( n ).
At STP, pressure is equal to 1 atm and Temperature is 273 K.
Convert volume in mL to L:
750 mL x 1 L / 1000 mL
= 0.75 mL
n = PV/ RT
= 1 atm ( 0.75 L ) / 0.0821 L.atm/ mole.K ( 273 K)
= 3.3x10-² moles H2
Convert moles of H2 to atoms using Avogadro's Number.
3.3x10-² moles H2/ 6.022x10²³ atoms H2 / 1 mole H2
= 1.99x10²² atoms H2
Answer:
The attraction of the soil to the inside of the surfactant micelle helps loosen the soil from its surface. Once the soil lifts off the surface, it becomes suspended in the water in the micelle. This suspension is also known as emulsification of one liquid into another.
