An atom becomes an ion when it gains or loses an electron. Remember, the elements are trying to gain the properties of a noble gas (full electron shells e.g. 2,8,8..). So Sodium has 11 protons (therefore it must have 11 electrons) and only 2 electrons can fill up the first energy level. Then the remaining 9 electrons must be placed into energy levels. The second energy level can only hold 8 electrons, so the additional electron must be placed into an energy level on its own.
It has the electronic structure 2,8,1. When it loses its electron to an element like Flourine, Sodium becomes a positive ion and the fluorine which has gained the electron becomes negative.
The symbol Na typically represents a neutral sodium atom with 11 protons and 11 electrons. If a sodium atom loses an electron, it becomes a positively charged sodium ion (Na+).
The element with 11 protons is sodium, and its elemental symbol is Na.
Sodium loses its one valence electron to become Na+
Sodium ionSodium, Na, becomes a single positive cation Na+
Not quite. The symbol Na+ represents a sodium ion that has lost one electron, giving it a net positive charge. It no longer behaves like a neutral sodium atom and is more reactive in forming compounds.
Na -> Na+ + e-
"Na" is the symbol of an atom of the element sodium.
surely i don't know sodium atom which can be gained 2 electrons but anyway i thought the answer is Na+2
The chemical equation for the formation of table salt (sodium chloride) is 2Na + Cl2 -> 2NaCl. This equation represents the combination of one sodium atom with one chlorine molecule to produce two sodium chloride molecules.
There is one dot around the Na in the Lewis symbol for a neutral atom of Sodium.
The symbol Na represents the element sodium.
The symbol Na typically represents a neutral sodium atom with 11 protons and 11 electrons. If a sodium atom loses an electron, it becomes a positively charged sodium ion (Na+).
Na^+ represents a sodium atom that has lost ONE ELECTRON.
The element with 11 protons is sodium, and its elemental symbol is Na.
Sodium is an atom. It is a chemical element with the symbol Na and atomic number 11. Sodium exists as single atoms and does not naturally occur as a molecule in its elemental form.
The chemical equation for the reaction between sodium and carbon is 2Na + C -> Na2C. This balanced equation shows that two atoms of sodium react with one atom of carbon to form sodium carbide.
