What can you balance with redox?
•1st- Non O, H elements •2nd- electrons lost and electrons gained •3rd- Oxygen •4th- Charge •5th- Check your H atoms
How many electrons are lost or gained in the element o when they form ions?
atoms gain and lose electrons, so they can have a full outer shell of 8 electrons (or two electrons if its the innermost shell) when atoms lose electrons it is called oxidation and when they gain electrons they are said to be reduced. OIL RIG is most commonly used to help remember that oxidation is loss and reduction is gain of electons. when atoms lose electrons they are left with a positive charge and when they can electrons they have a negative charge.
What are Atoms that carry an electrical charge called because they have gained or lost electrons?
Atoms that carry an electrical charge because they gained or lost electrons are called ions. An atom that has lost electrons will be positively charged, and it is called cation. On the other hand, an atom that has gained electrons will be negatively charged, and it is called anion.
What property of oxygen makes it share electrons unequally with hydrogen atoms?
Oxygen atoms have a greater electronegativity than hydrogen atoms. Electronegativity is the ability of an atom in a molecule to attract electrons to itself.
How can you justify that a reaction between magnesium and oxygen is a redox reaction whioe the reaction shows only addition of oxygen?
In any redox reaction, at least one reactant is reduced and at least one reactant is oxidized. In the reaction between magnesium and oxygen, the magnesium atoms are oxidized because they lose electrons and the oxygen atoms are reduced because they gain electrons. Furthermore, the premise of the question is erroneous: The reaction does not as alleged show only addition of oxygen; instead it shows combination of magnesium and oxygen to form a new chemical entity, the compound magnesium oxide.
What is a oxidation bond?
the bond in which electrons are lost or oxygen atoms are gained or hydrogen atoms are lost.
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.

What The double bond between carbon atom and two oxygen atoms has two characteristics what are they?
The answer is c. Valence electrons are shared between oxygen atoms & D. Four valence eletrons are shared
How many atoms valence electrons are in an oxygen atom?
Oxygen has six valence electrons.
What type of bond is formed when electrons are gained and lost?
Ionic bonds are formed between positively charged atoms (lost electrons) and negatively charged atoms (gained electrons).

When iron oxide is reduced?
To reduce a compound is to remove oxygen from it. Iron oxide can be reduced to iron by removing its oxygen atoms.
What property of oxygen makes it share electrons unequally with hydrogen atoms?
Oxygen atoms have a greater electronegativity than hydrogen atoms. Electronegativity is the ability of an atom in a molecule to attract electrons to itself.
Which two atoms an iconic bond?
Atoms that have lost one or more electrons form an ionic bond with an atom that has gained one of more electrons.
What is the number of valence electrons for atoms of oxygen?
6
