Answer:
Atoms are electrically neutral as a result of having an equal amount of positive (due to the protons) and negative (due to the electrons) charges on it.
An ion generally is an electrically unbalanced atom (i.e an atom with a net charge on it)
A negative ion called an anion is produced when an atom gains an extra electron from a neighboring atom, giving it an extra negative charge. This can be produced by ionization with a radioactive radiation or simply by dissolution.
A positive ion is called a cation and it is produced when an atom loses electron to a neighboring atom. The loss of this electron causes the positive charges to outweigh the negative charges in the atom. Cations can be produced by radioactive radiation ionization of an atom or by simple dissolution.
The subatomic particle that is negative is the 'electron'.
<span>Plants use carbon dioxide and sunlight to make their own food and grow the carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels most of the carbon quickly enters the atmosphere as carbon dioxide :) i love biology</span>
<span>If the density of ice were greater than water, ice would sink to the bottom of oceans/seas/lakes etc. This ice would cool the water so much that more water would freeze, and the entire body of water would soon be a giant block of ice! You can imagine how this would affect aquatic life</span>
Answer:
The easiest answer to that is that most of the water on Earth isn’t just water.
Explanation: Most of the water on Earth contains high levels of salt, and that’s a major cause for why so much of that water is not fit for human consumption. That much salt is toxic to humans because it overloads the kidneys’ ability to remove salt. Freshwater works in part by diluting and absorbing the salt in your body so it can be flushed out of your system, but salt water is so saturated in salt this just isn’t possible. Even worse, the salt in the salt water actually adds to the salt in your body, so when you are dehydrated, one of the worst thing you can do is drink salt water.
About 97% of the water on Earth is salt water. Of the remaining 3%, some of that will be unfit for human consumption because it was used in industrial processes or sanitation, and some of it will be unfit for human consumption because the water is home to parasites (and in some cases, the water is both).
As a sidenote, when I said that the remaining 3% of the water was not salt water, I didn’t say that it was available freshwater (tainted or otherwise). Most of the freshwater in the world is ground water, literally water that is found in the ground itself.
Hope that helped you <3 ;)
