This substance is called an Oxidant or an Oxidising Agent .
It oxidises the other substance and reduces itself .
This is when redox reactions comes in. reduction is gain of electrons oxidation is loss (mnemonic OIL RIG "oxidation is loss, reduction is gain")
Ion. Any atom that loses or gains an electron becomes an ion.
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
It can be positive or negative depending on if the atom loses or gains an electron. If it gains an electron it becomes negative and if it loses an electron it becomes positive.
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
Each caesium atom loses an electron and the oxygen atom gain two electrons (for Cs2O).
Potassium loses one electron.
A neutral atom, it only becomes an ion after it loses or gains an electron.
An Ion. More specifically if it gains an electron it becomes an anion and it it loses an electron it becones an cation (pronounced Kat-ion)
This is called a redox reaction. An atom that loses an electron is oxidized and an atom that gains an electron is reduced.
Ion. Any atom that loses or gains an electron becomes an ion.
Ion. Any atom that loses or gains an electron becomes an ion.
It become an ion, positively charged when it loses an electron (called a cation, e.g. Na+) or negatively charged when it gains an electron (called a anion, e.g. Cl-).
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
The atom that gains electron becomes an anion. The atom that loses electron becomes a cation.
It can be positive or negative depending on if the atom loses or gains an electron. If it gains an electron it becomes negative and if it loses an electron it becomes positive.
no
gains or loses an electron.
