They are important because they are the electrons that help the atom to bond with another atom. They are in the outer most shell. ☺️
Answer:
A solid's particles fit closely together. The forces between the particles are so strong that the particles can not move freely; they can only vibrate. This causes a solid to be a stable, non-compressible shape with a definite volume.
Explanation:
I honestly don't know if that's right...
The larger it is, the farther away the valence electrons is from the nucleus. This means that the pull is weaker, making it easier to pull the valence electrons away.
Answer:
The systematic name of the complex is: ![[Cu(en)_2(H_2O)_2]I_2](https://tex.z-dn.net/?f=%5BCu%28en%29_2%28H_2O%29_2%5DI_2)
diaquabisethylenediaminecopper(II) iodide
Explanation:
= Given complex whose naming is to be done:
Rules for naming of the coordination compounds :
- The name of ligand should be written first and then metal.
- The charge of metal indicated with the Roman numerals and enclosed in the parenthesis after metal name.
- The ligand's names written should be in an alphabetical order before the metal ion.
- Ligands that include a numerical prefix in the name use the prefixes bis or dia for 2, tris for 3, or tetrakis for 4 to indicate their number.
- If the complex ion is an anion, we drop the ending of the metal name and add –ate.
The cationic part of the complex: diaquabisethylenediamine copper(II)
The anionic part of the complex: iodide
The systematic name of the complex is: ![[Cu(en)_2(H_2O)_2]I_2](https://tex.z-dn.net/?f=%5BCu%28en%29_2%28H_2O%29_2%5DI_2)
diaquabisethylenediaminecopper(II) iodide
