How do you know how many an atom contains and how many electrons the entire ion has either lost or gained?

Chemistry

Mkey [24]3 years ago

If you mean how many electrons an atom contains then this is the same as the atomic number of the atom. For example, the atomic number of oxygen is 8 so it contains 8 protons. Since in a stable atom, the number of protons is equal to the number of electrons, oxygen contains 8 electrons.

If you have an ion and you want to know how many electrons it has lost or gained, you look at the charge. If it is a 2+ ion then it has lost two electrons, if it's a - ion then it has gained an electron. The number of electrons in an ion is the atomic number +/- the charge shown. For example a Mg2+ ion would have 10 electrons as a magnesium atom has 12 electrons and loses two to form the 2+ ion.

What causes some aqueous solutions to have a low PH?
noname [10]
<span> Low pH means the solution is acidic; if the solution is acidic, that means that there are hydronium ions in solution (H3O+). For example, hydrochloric acid dissolves into H+ ions and Cl- ions, and the H+ ions rreact with water like this:
H+ + H2O --> H3O+

If you want to get mathematical, pH is defined as the negative log of the concentration of hydronium ions.
Thus, if there are a lot of hydronium ions, the solution will have a low, or acidic, pH.  Hope this helps^-^</span>

I can't figure this problem out, please help
mario62 [17]
First you have to look at the mole ratios of the reactants and products and that ratio is 2:2:2 or you can reduce that to 1:1:1.  That means an amount of peroxide will produce the same amount of oxygen gas.  If there are 8 mol of peroxide will give 8 mol of oxygen gas

What element/compound is the most heat resistant and how much can it withstand?
Orlov [11]
Carbon and tungsten are the most common heat resistant elements known. Their melting points are approximately 3400 to 3800 degrees Celsius. Ceramic materials as well are known to be heat resistant inorganic solids. Ceramics are made up of metallic and nonmetallic elements.
