Look at the atomic number of an element on the periodic table which is the smaller number.
The atomic number shows the number of protons/electrons so the number of protons and electrons are the same.
Whereas the mass number of an element (the other number) is the number of protons + neutrons.
Answer:
1600/27 cubic yards
Explanation:
Convert each of the dimensions into yards, getting 10/3, 20/3, and 8/3. Multiply them all to get 1600/27
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
I don’t understand this one sorry
