Answer is: D. Cl (chlorine).
The ionization energy (Ei) is the minimum amount of energy required to remove the valence electron, when element lose electrons, oxidation number of element grows (oxidation process).
Barium, potassium and arsenic are metals (easily lost valence electrons), chlorine is nonmetal (easily gain electrons).
Alkaline metals (in this example, potassium) have lowest ionizations energy and easy remove valence electrons (one electron), earth alkaline metals (in this example, barium) have higher ionization energy than alkaline metals, because they have two valence electrons.
Nonmetals (in this example chlorine) are far right in the main group and they have highest ionization energy, because they have many valence electrons.
Answer:
depends on how you look at it. It means that they either think your fat and your shirt is too small or that your being too revealing and need to cover up your stomach.
Explanation:
Once before a guy got mad at me because of the same reason but it was only because he cared for my privacy and protection :)
Answer: The difference between rapid combustion and spontaneous combustion...
Explanation:
Rapid combustion is a form of combustion, otherwise known as a fire, in which large amounts of heat and light energy are released, which often results in a flame.Whereas spontaneous combustion is the ignition of organic matter (e.g. hay or coal) without apparent cause, typically through heat generated internally by rapid oxidation.
Answer:
Your answer could be: ceramic or stainless steel.
Explanation:
Glass, ceramic, and stainless steel are all good insulating materials for keeping coffee hot. Although, if you don't want to possibly burn yourself, don't use glass.
Have a great day/night! ^^
molar mass of PF5 = 125.966 g/mol
125 g PF5 × (1 mol PF5/125.966 g PF5) = 0.992 mol PF5
0.992 mol PF5 × (6.022 × 10^23 molecules PF5);
= 5.97 × 10^23 molecules PF5
Since there 5 fluorine atoms per molecule of PF5,
(5.97.× 10^23 molecules PF5) × (5 atoms F/1 molecule PF5)
= 2.99 × 10^24 atoms F
