(2) Energy is absorbed as a bond is broken.
(3) Energy is released as a bond is formed.
(4) Energy is released as a bond is broken.
Answer:
The correct answer is option 3.
Explanation:
Whenever there is a formation of bond between 2 atoms energy is released. This energy release is due to stability gained by the atoms after the formation of a bond that is why extra energy is released as a heat into surroundings. Exact process is occurring when 2 bromine atoms form bond to give molecule of bromine.
Whenever there is a dissociation of bond between 2 atoms energy is given. The energy provided externally so as to break the stable bond present between the atoms.
(1) 18 (3) 10
(2) 16 (4) 8
The total number of neutrons in an atom of O-18 is 10. This is determined by subtracting the atomic number (number of protons) from the atomic mass (number of protons + neutrons).
To find the number of neutrons in an atom, you subtract the atomic number (number of protons) from the atomic mass (number of protons + neutrons). In an atom of O-18 (Oxygen-18), the atomic number of oxygen is 8, which means there are 8 protons. The 18 in O-18 represents the atomic mass. Subtracting the atomic number (8) from the atomic mass (18) gives us the number of neutrons, which is 10.
