Answer:
The answer to your question is:
Explanation:
1) Increasing atomic radius:
Oxygen 74
Aluminum 143
Potasium 227
2) Increasing electronegativity
Neon -
Aluminum 1.61
Sulfur 2.58
Oxygen 3.44
3.-
Electronegativity: is the measure of the tendency of an atom to attract a pair of electrons.
Ionization energy: is the quantity of energy that an isolated, gaseous atom must absorb to discharged an electron, resulting in a cation.
4.-
Atomic radius increases as we move down on the periodic table.
Atomic radius is the distance from the center of a nucleus to the outer most shell containing electrons.
5.-
Sulfur = 1s² 2s² 2p⁶ 3s² 3p⁴
Neon = 1s² 2s² 2p⁶
The correct option is B.
After sorting the drugs into two groups, it is very important to check with the client, who is the one using the drugs, in order to ensure that the drugs have been properly sorted and no mistake was made. After ensuring that the drug has been accurately sorted then the ones that the client is no longer using can be put away in an appropriate safe location in order to avoid mix up.
Br
First of all, As is a metalloid, not a nonmetal. Second of all, as the rows get higher on the periodic table, the elements are more reactive. As you move right on the periodic table, the elements become more reactive.
Answer: The total potential energy of the products is less than the total potential energy of the reactants
Explanation:
Answer:
approximately 106 grams
Explanation:
The molecular mass of Aluminum Oxide is approximately 102 grams per mole.
2×Al=
2×27=54
3×O=3×16=48
54+48=102
200
102
=1.96 moles
There are two atoms of Aluminum in one mole and each atom has a mass of approximately 27 grams so
Mass of Al = 1.96×2×27=106 grams
