Your answer would be, Sugar is the solute, and water is the solvent. a solution is the mixture of two, or more substances.
Hope that helps!!!
Answer:
A. The accepted model of the atom was changed.
Explanation:
Thomson described an atom that has the protons uniformly distributed within a circular atom with the electrons embedded . However, it cannot explain the emission of electrons from the surfaces of metals like photoelectric emission. it does not explain how the particle of the atom contribute significantly to the entire mass of an atom
The given complex Ion is,
[Co(CN)₃]³⁻
In complex compounds the Positive part is named first, followed by name of Negative part. In given case there is no Positive part. So, we will name the Negative part.
In Sphere the Ligands are named first. In this case there are 6 CN⁻ ligands. As CN⁻ (cyanide) contains a negative charge so the -ide is replaced by -o. i.e. Cyanide → Cyano. Also, Hexa is placed before Cyano as there are 6 CN⁻ Ligands.
So,
Hexacyano
After that Chromium metal is named. As there is a negative charge on the sphere, so the -ium in Chromium is replaced by -ate.
i.e. Chromium → Chromate. And the oxidation state of Cr is written in Roman. Hence,the name is as,
Hexacyanochromate (III) Ion
Answer:
The answer to your question is: Fluorine, Chlorine, Bromine, Iodine
Explanation:
Electron configuration ns² np⁵
We observe that this electron configuration finishes in "p". Elements from groups IIIA to VIIIA finish their electron configuration in "p".
Elements in Group IIIA finish in p¹
Group IVA finish in p²
Group VA finish in p³
Group VIA finish in p⁴
Group VIIA finish in p⁵
Group VIIIA finish in p⁶
Then, the list of elements with this electron configuration is:
Fluorine, Chlorine, Bromine, Iodine
