Answer:
An atom behaves electically neutral because it has an equal number of protons and electrons.
Explanation:
There are three sub-atomic particles: neutrons, electrons and protons. Neutrons have a neutral charge; electrons have a negative charge; and protons have a positive charge. In a regular atom, there is an equal amount of electrons and protons, making a neutral charge.
To make everything easier to convert so everything universal
Answer:
3
Explanation:
Atoms are made of 3 parts.
- The protons and Neutrons form together creating a sun, or nucleus at the center
- The electrons orbit this sun like planets.
The element with Th is Thorium. It is a metallic chemical element that when exposed to air, hardens.
Answer:
Benzoic acid, anthracene
Explanation:
If you have a compound with an aqueous layer and organic layer, they can be distinguished by adding distilled water. The aqueous layer increases in size.
Organic products are soluble in organic solvent (organic layer). Benzoic acid, anthracene are both acidic, therefore if you perform an extraction with acidic aqueous solution both would dissolve in the methylene chloride thereby remaining in the organic layer.
