which is the symbol for the following monatomic ion?
8 protons and 10 electrons
The 8 tells you to look on the periodic table at element #8, which is oxygen. Neutral oxygen has 8 protons and 8 electrons. Since this question shows oxygen with 10 electrons, it means it must have a -2 charge. The symbol is O=.(O with a negative 2 charge); i.e., the oxide ion.
To determine the symbol for a monatomic ion with 8 protons and 10 electrons, we first need to determine the charge of the ion.
In a neutral atom, the number of electrons is equal to the number of protons. However, if the number of electrons is different from the number of protons, the atom becomes an ion.
Since the ion has 8 protons, we can assume it is an oxygen atom (O) since oxygen has 8 protons. If the atom has 10 electrons, it means it has gained 2 electrons, resulting in a negative charge.
Therefore, the symbol for the monatomic ion with 8 protons and 10 electrons is O^2-.
To determine the symbol for the monatomic ion with 8 protons and 10 electrons, you need to find the atomic number and determine the charge on the ion.
The atomic number tells you the number of protons in an atom's nucleus, which also defines its identity. Since you have 8 protons, you are dealing with the element oxygen (O), as it has 8 protons.
To find the symbol for the ion, you need to determine the charge. Since ions are formed by gaining or losing electrons, the charge can tell you if the ion is positively or negatively charged. In this case, you have 2 more electrons (10 total) compared to the usual 8 electrons in a neutral oxygen atom.
To get a negative charge, the ion must have gained 2 extra electrons. Therefore, the symbol for the monatomic ion with 8 protons and 10 electrons is O^2-.
