'अ' गटातील घटकांना 'ब' गटात एकापेक्षा जास्त बरोबर पर्याय उपलब्ध असू शकतात. 'अ' गट 'ब' गट I. 10 इलेक्ट्रॉन्स अ. ²⁰₁₀Ne II. 12 प्रोटॉन्स ब. ²³₁₁Na⁺ III. 12 न्युट्रॉन्स क. ¹⁹₉F⁻ IV. 10 न्युट्रॉन्स ड. ²⁴₁₂Mg²⁺ पर्याय उत्तरे : You may have more than one correct match in Group 'B' for each item in Group 'A'. Group A Group B I. 10 electrons a. ²⁰₁₀Ne II. 12 protons b. ²³₁₁Na⁺ III. 12 neutrons c. ¹⁹₉F⁻ IV. 10 neutrons d. ²⁴₁₂Mg²⁺ Answer Options :

1)I - a; II - d; III - b, d; IV - a, c
2)I - a, c; II - d; III - b, d; IV - a
3)I - a, b, c, d; II - d; III - b, d; IV - a, c✓ Correct
4)I - a, b, d; II - d; III - b; IV - a, b, c

Detailed electron, proton, and neutron calculations for Ne, Na+, F-, and Mg2+ match multiple criteria across the groups due to isoelectronic and isotopic relationships.

ऑक्सीजन निसर्गात किती आइसोटोप्स मध्ये आढळतो? / Oxygen occurs in nature in ________ isotopic forms.

1)2
2)3✓ Correct
3)4
4)1

Oxygen occurs naturally in three stable isotopic forms: Oxygen-16, Oxygen-17, and Oxygen-18.

ज्या केंद्रभागांचे अणुक्रमांक आणि अणु वस्तुमान विविध असतात, पण न्यूट्रॉनची संख्या समान असेल, तर त्यांना ________ म्हणतात. If nuclides have different atomic numbers and different atomic masses but the same number of neutrons, then they are known as

1)Isotopes
2)Isobars
3)Isotones✓ Correct
4)None of the above

Nuclides with different atomic numbers and mass numbers but the exact same number of neutrons are known as Isotones.
