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.
What else can I help you with?
The symbol Na represents a sodium atom that has lost an electron?
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+).
What is the elemental symbol for an atom with 11 protons?
The element with 11 protons is sodium, and its elemental symbol is Na.
Does a sodium atom lose or gain electrons when it becomes an ion?
Sodium loses its one valence electron to become Na+
What does a sodium atom become when it loses its only valence electrons?
Sodium ionSodium, Na, becomes a single positive cation Na+
The symbol Na plus represents a sodium atom that has lost an electron?
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.
Write an equation that shows the formation of a sodium ion from a neutral sodium atom.?
Na -> Na+ + e-
Is na an atom or an element?
"Na" is the symbol of an atom of the element sodium.
What is the symbol for a sodium atom which has gained two electrons?
surely i don't know sodium atom which can be gained 2 electrons but anyway i thought the answer is Na+2
What is the chemical equation that shows sodium and chlorine combining to form table salt?
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.
How many dots are around the Na in the Lewis symbol for an neutral atom of Sodium?
There is one dot around the Na in the Lewis symbol for a neutral atom of Sodium.
How many atoms are represented by the symbol Na?
The symbol Na represents the element sodium.
The symbol Na represents a sodium atom that has lost an electron?
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+).
What symbol Na plus represents a sodium atom that has lost?
Na^+ represents a sodium atom that has lost ONE ELECTRON.
What is the elemental symbol for an atom with 11 protons?
The element with 11 protons is sodium, and its elemental symbol is Na.
Is sodium an atom or molecule?
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.
What is the equation of sodium and carbon?
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.
What is formed when a sodium atom and chlorine atom reacts chemically?
study
