An element is represented by ZXA, where Z is atomic number which is also equal to number of proton, A is mass number and X is symbol of the element. Mass number (A) = Number of protons (Z) + Number of neutrons. Isoelectronic: Species/ elements having same number of electron Isodiaphers: Elements having same value of |(A−2Z)| Isotopes: Atoms having same number of proton Which of the following is a pair of isodiaphers?

1.	An element is represented by ZXA, where Z is atomic number which is also equal to number of proton, A is mass number and X is symbol of the element. Mass number (A) = Number of protons (Z) + Number of neutrons. Isoelectronic: Species/ elements having same number of electron Isodiaphers: Elements having same value of \|(A−2Z)\| Isotopes: Atoms having same number of proton Which of the following is a pair of isodiaphers?
Answer» An element is represented by $_{Z} X^{A}$ , where Z is atomic number which is also equal to number of proton, A is mass number and X is symbol of the element. Mass number (A) = Number of protons (Z) + Number of neutrons. Isoelectronic: Species/ elements having same number of electron Isodiaphers: Elements having same value of $\| (A - 2 Z) \|$ Isotopes: Atoms having same number of proton Which of the following is a pair of isodiaphers?
