assertion - reason question a) assertion: atoms are indivisible reason: atoms cannot be seen with the naked eye. b) assertion: ozone has three molecules of oxygen in it. c) assertion: ions are charged paticles. reason: ions are formed by the loss of electrons. d) assertion: the atomic mass of an element is the same as the mass of the ion of the element. reason: atomic mass does not depend on a number of electrons in an atom. E) assertion: law of conservation of mass states that mass is conserved in a chemical reaction reason: atoms are indivisible.
Answers
Answer:
A) Because atoms are too. Small in size we can't see atoms....
B) Ozone (O3) is a triatomic, molecule, consisting of three oxygen atoms. Ozone in the upper atmosphere protects living organisms by preventing damaging ultraviolet light from reaching the Earth's surface. O3 is the formula for ozone. It has three oxygen atoms.
C) Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet. In cases where an atom has three or fewer valence electrons, the atom may lose those valence electrons quite easily until what remains is a lower shell that contains an octet.
D) Assertion :The atomic mass of an element is same as mass of the ion of the element. Reason : Atomic mass does not depend on number of electrons in an atom. ... Reason: Atoms are indivisible..
E) According to Dalton's theory atoms are indivisible particles and cannot be created nor destroyed.
