Answer:
Explanation:
The net force on electron is electrostatic force between electron and proton in the nucleus .
Fc = 
This provides the centripetal force for the circular path of electron around the nucleus .
Centripetal force required = 
So



Answer:
they both gain one electron
Explanation:
they are both halogens and they each have one unpaired electron so that unpaired electron join together to make them form a bond
The answer is A. Water
Bronsted-Lowry base compounds are those that can accept protons
Bronsted-Lowry Acid Compounds are those that can recieve one
Water / H2O is an Amphoteric compund which mean that its molecul can act as a Base and Acid compound, so the answer is A.
Non-metals, which are organized on the right side of the periodic table, have higher electronegativity values than the metals.
