Ions are formed when elements gain or lose electrons.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
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.
Metals have a low number of valence electrons, so it is favorable for metals to lose electrons to form positive metallic ions and gain a complete v.e. shell.
The two groups that do not usually form ions include Group 14 and Group 18. Group 14 does not form ions. They do not gain or lose electrons either. Group 18 does not form ions because they contain stable noble gases.
No. Atoms of an element lose or gain electrons to form ions.
When atoms lose or gain electrons, they form ions. These are charged particles.
No. They gain electrons
Neither. It does not form ions.
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.
Acids lose hydrogen ions.
They can do both to form ions. An ion simply means that there is an uneven distribution of charge, so it can be positive or negative.
1. Gain an electron. 2. Lose an electron.
Electrons
Ions are atoms that have lost or gained electrons. The number of protons in an atom remains unchanged but with loss or gain of electrons the charges becomes unbalanced, because the number of electrons is NOT equal to the number of protons. Ions can be divided into two viz. Cations ( positively charged) and Anions ( negatively charhed(. Here are some examples. Sodium atom has 11 protons(+) and 11 electrons(-). Sodium cation has 11 protons(+) and 10 electrons(-) If we do a little sum (+)11 - 10 = (+)1 This is indicated on the sodium cation as Na(s) = Na^(+) + e^(-) Similarly Calcium atom has 20 protons(+) and 20 electrons(-). Calcium cation has 20 protons(+) and 18 electrons(-) If we do a little sum (+)20 - 18 = (+)2 This is indicated on the calcium cation as Ca(s) = Ca^(2+) + 2e^(-) Conversely Chlorineatom has 17 protons(+) and 17 electrons(-). Chloride anion has 17 protons(+) and 18 electrons(-) If we do a little sum (+)17 - 18 = (-)1 This is indicated on the chloride anion as Cl(g) = Cl^(-) - e^(-) Similrly Oxygen atom has 8 protons(+) and 8 electrons(-). Oxide anion has 8 protons(+) and 10 electrons(-) If we do a little sum (+)8 - 10 = (-)2 This is indicated on the chloride anion as O(g) = O(2-) - 2e^(-) So ions are charged atoms. Or Ions have a charge, Atoms have no charge. Chemically, charged atoms are no longer atoms but IONS.
Ions are formed when elements gain or lose electrons.
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
