What are the polyatomic ions?
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.
When do you need to use a roman numeral in the name of a compound?
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.
The difference between a positive and a negative charged atom?
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.
What come in these two flavors positive and negative?
Lots of things. Some of these are: Electrical charge, Ions, Attitudes, Feedback,
What is a double-replacment?
A double replacment is a way of forming a new homogenous mixture. Generally double-replacement reactions involve the exchange of positive ions between two reacting compounds. Typically the compounds are in aqueous solution and are often characterized by the production of a precipitate. Explained: When dealing with two ionic compounds dissolved in water to form a homogenous mixture, there are two possiblities when they are mixed togeather. *They form a new homogenous mixture *A chemical reaction will occur,
What kind of ions do metals form and what kind of ions do nonmetals form?
Metals for positively charged ions and nonmetals form negatively charged ions.
Are forms negative ions metals or nonmetals?
Negative ions are formed when an atom gains one or more electrons, making them nonmetals. Metals tend to lose electrons to form positive ions.
Do non-metals become positive or negative as 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.
What has the greatest chance to lose electrons and become positive ions Metals or Nonmetals?
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.
What type of ions will nonmetals form?
Metals form cations and non-metals form anions.
What are the key differences between metals and nonmetals on the periodic table?
Metals are typically shiny, malleable, and good conductors of heat and electricity, while nonmetals are often dull, brittle, and poor conductors. Metals tend to lose electrons to form positive ions, while nonmetals tend to gain electrons to form negative ions.
What type of elements form positive ions and what are positive ions called?
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.
How do ions in metals behave?
Metals form positive ions (cations).
Does metals react with non metals?
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
When metals combine with nonmetals the metallic atom tends to?
lose electrons and form cations.
What elements can form a positive ion?
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.
What has positive ions and can form ionic compounds?
Metals form positive ions and form ionic compounds with negative ions.
