. Give reason for the following a) Isotopes of an element are chemically similar b) An atom is electrically neutral c) Noble gases show least reactivity d) Nucleus of an atom is heavy and positively charged. e) Ions are more stable than atoms.
Answers
b) atoms are electrically neutral because they have equal numbers of protons and electrons. if an atom loses or gain one or more electron it becomes an ion.
c)noble gases show least reactivity because they already have a filled valence shell of electrons. a noble gases has no need to gain or loss electrons to gain a stable electron configuration.that doesn't mean that noble gases are completely inert.
d)because it consist of both protons and neutrons.so its heavy.
e)the ions so arrange themselves that the positive and negative charges alternate and balance one another out.
I hope it will help you:)
a) they have similar chemical properties because isotopes of an element have the same number of electrons as an atom of that element. the electron arrangement is the same owing to same chemical properties.
