Answer:
The correct answer is A and D.
Explanation:
Please I want brainliest.
Reason:
The size of the ions follows the order:
Negatively charged ion > Neutral atom >
Positively charged ion
This is because of the size of ions increases when the electrons are added to the outermost shell of an atom.
This happens due to the increase in
electron-electron repulsion.
Moreover, when the electrons are removed from an atom, then the affective nuclear charge that is experienced by the outermost electron increases.
Thus the size of the positively charged ion is least.
The second one is more concentrated as they both times with the same thing but the second one (1.5) is bigger
It's 1. Melting a substance. The rest are chemical changes
Answer:most of the positively charge particles should be bounce back at a range of angles as they collide with the atoms in the foil; only a few should pass straight through the foil
Explanation:
Three examples of environmental, industrial and bio-chemistry are listed below:
- Environmental chemistry: Contamination, Atmospheric Deposition, and Soil Pollution.
- industrial chemistry: industrial inorganic chemicals, industrial organic chemicals, and agricultural chemicals
- bio-chemistry: genetic, immunology, and enzymology
<h3>Meaning of Chemistry</h3>
Chemistry can be defined as a branch of science which is concerned with the substances matter is composed of, their properties and reactions,
Chemistry also deals with the use of such reactions to form new substances.
In conclusion, Three examples of environmental, industrial and bio-chemistry are listed anove
