📖 Comprehensive Note
Isotopes are atoms of the same chemical element that have the same number of protons but a different number of neutrons.
- Definition: Isotopes are variants of an element with equal atomic numbers but different mass numbers.
- Protons: Same for all isotopes of an element.
- Neutrons: Different in each isotope.
- Properties: Identical chemical properties, different physical properties (like mass).
- Example: Carbon-12, Carbon-13, Carbon-14.
Isotopes play a key role in dating fossils, medical imaging, and nuclear science.
🎤 Lyrics
Verse 1
An isotope is a variant of a
Chemical element
That has the same number
Of protons but
A different number of
Neutrons in its atomic nucleus.
Chorus
Isotopes of an element
Have identical chemical properties
But different atomic masses.
Verse 2
An isotope is a variant of a
Chemical element
That has the same number
Of protons but
A different number of neutrons in its atomic nucleus.
An isotope is a variant of a
Chemical element
That has the same number
Of protons but
A different number of
Neutrons in its atomic nucleus.
Chorus
Isotopes of an element
Have identical chemical properties
But different atomic masses.
Verse 2

That has the same number
Of protons but
A different number of neutrons in its atomic nucleus.

| Concept | Explanation |
|---|---|
| Isotopes | Atoms of the same element with same protons but different neutrons. |
| Atomic number | Same for all isotopes of an element. |
| Mass number | Varies due to differing neutrons. |
| Chemical properties | Remain identical among isotopes. |
| Examples | Carbon-12, Carbon-13, Carbon-14. |
💡 Mnemonic
"ISO = Same, TOPES = Type" — Isotopes are the same type of element with different neutrons.
