Few, one to three.
Alkaline earth metals have 2 electrons in their outer shell.
There are 3 electrons in the outer shell of aluminum.
Metals generally have 1 to 3 electrons in their outer shell. These outer shell electrons are loosely held and can be easily lost, which is why metals tend to form positive ions in chemical reactions.
Alkali metals have 1 electron in their outer shell.
Alkali earth metals have 2 electrons in their outer energy level. This outer level is known as the valence shell, and having 2 electrons makes these metals highly reactive and likely to form ionic bonds to achieve a full outer shell of 8 electrons.
Most metals and nonmetals form chemical bonds by transferring electrons to achieve a stable electron configuration with a filled outer shell, usually with 8 electrons. This transfer of electrons leads to the formation of ionic bonds between metals and nonmetals.
Metals react with non-metals to achieve a stable electron configuration. Metals tend to lose electrons to achieve a full outer shell, while non-metals tend to gain electrons to fill their outer shell. This transfer of electrons between metals and non-metals results in the formation of ionic compounds.
Thrse electrons are involved in chemical reactions.
poor metals have four, five, six..... electrons in its outermost shells these poor metals are also known as non-metals.
Noble gases have a full outer shell, meaning that they have no valence electrons and have 8 electrons in their outer shell. If the outer shell is full they do not need electrons, so they would not want to bond with another element to form a compound.
Normally, three.
NO. Nonmetals tend to GAIN electrons to complete their outer shell. By gaining electrons, they become a negatively charged species, which is what an anion is. Metals tend to LOSE electrons to end up with a full outer shell; in losing electrons, they develop a positive charge (become cations).
