How many electrons are in valence shell of a sodium atom before and after reaction with chlorine gas to give sodium chloride NaCl?
A sodium atom has 1 electron in its valence shell, while a chlorine atom has 7 electrons in its valence shell. When sodium reacts with chlorine to form sodium chloride, the sodium atom loses its 1 electron to achieve a stable octet configuration, while the chlorine atom gains this electron. The resulting sodium chloride molecule has 8 electrons in the valence shell of the chlorine atom.
If a sodium atom loses its only valence electron to another atom what does it become?
If a sodium atom loses its only valence electron, it becomes a sodium cation (Na+). This is because it has lost a negative electron, leaving behind a positively charged ion.
How many electrons are in the outermost orbital in one atom of sodium?
One atom of sodium has one electron in its outermost orbital.
How many electron are in an neutral atom of sodium?
11 electrons in a neutrally charged atom of sodium . It is the same number as the number of protons and the Atomic Number. However, the sodium ion (NOT Atom) has lost one electron , so there are now 11 protons(+), and 10 electrons(-). Hence 11(+)10(-)= 1(+) Hence the sodium ion is written as 'Na(+)'.
What kinds of ions do a sodium atom and a chlorine atom become when a valence electron is transferred from one the the other?
The sodium atom becomes a positive ion (Na+) when it loses a valence electron, and the chlorine atom becomes a negative ion (Cl-) when it gains a valence electron. This transfer of electrons creates an ionic bond between them, forming sodium chloride (NaCl), or table salt.
How many electrons are transferred in the ionic bonds between sodium and chlorine in NaCI?
The single valence electron of a neutral sodium atom is transferred to the valence shell of a neutral chlorine atom to form the stated bond; therefore, the answer is 1.
how number of valence electrons sodium have?
A sodium atom has one valence electron.
How many valence electrons does an atom of potassium have?
4
What is meant by the term ion when a sodium changes from an atom to an ion?
An ion is a charged particle. A sodium atom is neutral and has one electron in the valence shell. When it loses its valence elctron, it is no longer neutral and becomes Na+ , i.e a charged particle, hence it is an ion.
The numbers in a valence electron in a neutral atom is?

How many electrons are in valence shell of a sodium atom before and after reaction with chlorine gas to give sodium chloride NaCl?
A sodium atom has 1 electron in its valence shell, while a chlorine atom has 7 electrons in its valence shell. When sodium reacts with chlorine to form sodium chloride, the sodium atom loses its 1 electron to achieve a stable octet configuration, while the chlorine atom gains this electron. The resulting sodium chloride molecule has 8 electrons in the valence shell of the chlorine atom.
Which of these is the correct Lewis structure for a sodium atom?
The electron-dot structure of sodium atom is 'Na-dot' or 'Na.' One dot is one valence electron.
If a sodium atom loses its only valence electron to another atom what does it become?
If a sodium atom loses its only valence electron, it becomes a sodium cation (Na+). This is because it has lost a negative electron, leaving behind a positively charged ion.
How many valence electrons does sodium 24 have?
Every sodium atom has only one valence electron.
Is Na plus a ion?
The Na+ ion is a sodium atom that has lost an electron and therefore has a single positive charge. Because a neutral sodium atom has one valence electron, it will usually form such an ion when it enters a chemical compound.
How many valence electron does oxygenatoms have?
A neutral oxygen atom has six valence electrons.
When K is neutral how many valence electrons does it have?
Potassium atom has 1 valence electron
