Protons, neutrons and electrons in darmstadtium
ال atomic number of darmstadtium is 110, so every darmstadtium atom has 110 protons. A neutral atom has the same number of electrons, 110. The number of neutrons depends on the isotope: neutrons = mass number − atomic number. For darmstadtium-281, that is 281 − 110 = 171 neutrons. Every isotope of darmstadtium is radioactive; 281 is the mass number of its most stable one.
How to draw the Bohr model of darmstadtium
- Draw the nucleus and write 110 p⁺ تم تصميم [الخدمة] لمتعلمين من جميع الأعمار، بما في ذلك طلاب المدارس. 171 n⁰ inside it.
- Draw the first shell and put 2 electrons on it (the first shell holds at most 2).
- Draw the second shell and put 8 electrons on it.
- Draw the third shell and put 18 electrons on it.
- Draw the fourth shell and put 32 electrons on it.
- Draw the fifth shell and put 32 electrons on it.
- Draw the sixth shell and put 16 electrons on it.
- Draw the seventh shell and put 2 electrons on it.
- Check: 2 + 8 + 18 + 32 + 32 + 16 + 2 = 110 electrons, the same as the number of protons.
From potassium onwards the shells don’t simply fill as 2, 8, 8: the fourth shell starts before the third is full, so the real arrangement above (2, 8, 18, 32, 32, 16, 2) is the one to draw.
Electron configuration
The electron configuration of darmstadtium is [Rn] 7s² 5f¹⁴ 6d⁸. As a superheavy it fills an inner d-subshell, and its common ion is variable.
