Number of valence electrons.
This is because an elements valence electrons determine its bonding and all the rest of its properties. All elements in a group will have similar properties because they all have the same number of valence electrons, aka group number.
.
Answer:
The answer is 6 valance electrons because it is oxygen and oxygen needs two more electrons to be a noble gas
Explanation:
Answer:
dilution
Explanation:
a solution which contains small amount of solute dissolve in large amount of solvent is called dilutEd solution.. dilutEd solution is prepared when a small amount of solute is dissolve in large amount of solvent..
Answer:
E. potassium (K) and bromine (Br)
Explanation:
An ionic bond is formed between compounds with a large electronegativity difference between them. It is usually between a metal and non-metal.
- Potassium is a true metal found in group 1 on the periodic table.
- Bromine is a highly electronegative non-metal which is a halogen.
- Potassium will lose one of its electrons which will be gained by the Bromine.
- The electrostatic attraction between the two species will cause the ionic bond to form.
- The ability of one specie willing to lose electron and the other gaining, is the main bed rock of ionic bonding.
The overall charge of the plum pudding model was neutral with negative charged electrons embedded in the positive charged proton.
