Ions are electrically charged particles, meaning, that whenever any type of atom loses or gains electrons it is forming a new type of structure, or ion.
Metal atoms form postive ions, Non-Metals form negative ions.
The strongest type of bond that can occur between two ions, when they are oppositely charged, are Ionic Bonds. The most commonly known ionic bond is seen in Sodium and Chlorine, which when combined give us NaCl or Sodium Chlorine, aka Salt.
+1 charge = Group 1, Metals
+2 charge = Group 2, Alkali Metals
-1 charge = Group 17, Halogens
Provided is a periodic table marked with the charges for each group.
Sodium Phosphide has a formula of Na3P . In order to bond ionically the charges must be equal and opposite. It will take one -3 phosphide ion to balance three +1 sodium ions forming a magnesium phosphide molecule of Na3P
Answer:
Explanation:
Combustion releases energy in a single step in the form of light and heat. Whereas in respiration, energy is released in steps and is stored in the form of ATP.
The answer is B. Molecules move more quickly as temperature increases.
When Allmond molecular motion stops, that is considered absolute zero. That does not mean that it cannot get colder, disapproving A.
C is just wrong.
D says when molecular motion stops the temperature STARTS to decrease, it was decreasing before it got there.
