polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.
First, if it is charged it is called an 'ion' and if it is positively charged it has lost one or more electrons from its outer parts and if it is negatively charged it has captured one or more electrons into its outer parts - as compared with its ground state which is when it has the same number of negative electrons in its outer parts as there are positively charged protons in its center and is therefore electrically neutral. all atoms are neutral, they have the same number of negatively charged electrons as they have positively charged protons (which is equal to the atomic number of that atom). metals can lose all of their valence electrons to get a complete outer orbital electron configuration, to form positively charged cations (+1, +2, and +3). They lose negatively charged electrons so they end up positive. ions are not atoms, they are atoms that have lost electrons or non-metals can gain electrons to fill their valence orbitals (becoming -1, -2, or -3). these nonmetals with extra electrons are anions, but anions are not atoms, they are atoms with extra electrons.
Typically use use the Roman numeral with a metal after a metal in an ionic compound to indicate which ion is indicated in the compound. The reason for this is that many metals can form more than one kind of ion. For example, copper can form Cu+ ions or Cu2+ ions, and iron can form Fe2+ ions and Fe3+ ions.
Lots of things. Some of these are: Electrical charge, Ions, Attitudes, Feedback,
The 3+ indicates that Aluminum has a positive charge of three due to the fact that it has lost three ions.
Metals for positively charged ions and nonmetals form negatively charged ions.
Negative ions are formed when an atom gains one or more electrons, making them nonmetals. Metals tend to lose electrons to form positive ions.
Non-metals typically become negative ions when they form ions because they gain electrons to achieve a full outer electron shell. This results in a negative charge due to the extra electrons present in the ion.
Metals have a greater tendency to lose electrons and form positive ions compared to nonmetals. This is because metals typically have fewer outer electrons which makes it easier for them to lose those electrons and achieve a stable electron configuration.
Metals form cations and non-metals form anions.
The elements that lose electrons and form positive ions are called metals. They will lose the electrons from their highest levels of energy to gain a more positive charge and form positive ions.
As far as I know, non-metals like Carbon(C) and Sulphur(S) do not react with water. They are tightly binded, so they are insoluble too. Chilax
Metals form positive ions (cations).
lose electrons and form cations.
Elements can form a positive ion by losing electrons to achieve a stable electron configuration. Metals are more likely to form positive ions by losing electrons, while nonmetals tend to gain or share electrons to form negative ions.
Nonmetals typically form anions when they gain electrons during chemical reactions. This results in the formation of negatively charged ions.
Metals form positive ions and form ionic compounds with negative ions.
