Sodium is in group 1A, therefore giving it one valence electron (outer ring) and causing it to lose the one electron it has. (The favorable number is 8, so if an atom has 6 valence electrons, it will take two electrons from another atom instead of losing six.)

∙ 9y agoOrdinarily, a sodium atom loses one electron to form a cation with the electronic configuration of a neon atom. This changes the outermost layer of the sodium ion from level 3 to level 2, which contains 8 electrons. Whether one wants to describe this as filling the "outer energy level of sodium" is a matter of taste. To actually fill what would normally be considered the "outer energy level of sodium" would require adding 7 electrons, but such an anion probably could not exist more than a few microseconds at most except at very small concentrations in laboratory apparatus, if even then.

Sodium is in group 1 of the Periodic Table. This therefore means that it has 1 electron in its outer shell. To become stable as an ion, it is easier to lose 1 electron than gain 8 electrons, so sodium has to lose 1 electron.

How many electrons are in a sodium cation Na plus?
The number of electrons is 10.
How many electrons does Na donate?
Sodium is a metal element. There are 11 electrons in a single atom.
How many electrons does NA has in outer most shell?
there is only one electron in the outermost shell of Na.
How are cation formed?
Cations are formed when they give up electrons in ionic bonding.
What is the meaning of metal ions?
A metal ion is a metal atom that has either lost or gained an electron (although most metals tend to lose electrons rather than gain them). Any atom that has lost or gained one or more electrons is called an ion. A metal ion is thus a metal atom with a charge. Some examples are Fe3+ (iron with a plus three charge, or that lost three electrons), Ag+ (silver ion with a plus one charge) and Cu2+ (copper with a plus 2 charge).
What is an atom that has gained or lost electrons causing an elctric charge?
An ion. Eg Na atom loses one electron to become Na+
What are the two possibilities that will happen to a valence electron during bonding?
During ionic bonding, the valence electrons are either lost or gained, depending on which group the element is. eg. Na + Cl --> Na+ + Cl- Na has lost an valence electron and Cl has gained an that electron. During covalent bonding, the valence electrons are shared between two atoms. eg. 2H2 + O2 --> 2H2O In H2O, each Hydrogen atom shares one pair of electrons with Oxygen by forming a covalent bond.
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 subatomic particles is lost or gained during a chemical reaction?
No. All of the elements, and their amounts will be present in the product/s, but they will be arranged differently.2Na + Cl2 --> 2NaClIn the balanced equation for the synthesis of sodium chloride (NaCl), the amount of sodium (Na) and chlorine (Cl) is the same on both sides.
What is a type of chemical bond where atoms gain or lose electrons?
Ionic bonds are formed when electrons are gained or lost. This is the complete transfer of electrons between the atoms. For e.g sodium(Na) releases its one electron which is transfered to the deserving chlorine atom(Cl). So, chlorine becomes negatively charged and the sodium atom becomes a positive ion(Na+). This is the case when electrons are completely transfered from sodium to chlorine and ionic bond is formed i.e NaCl. Moreover, when electrons are shared between atoms covalent bonds may form.
How many electrons in the NA?
eleven
How are oxidation numbers decided?
The number of electrons needed to be lost/gained to gain a stable electronic structure. For example, Sodium needs to lose just 1 electron to make its electronic structure stable, so the ion it forms is Na+ .
How many electrons are in a sodium cation Na plus?
The number of electrons is 10.
What are the differences between natural atoms and ions?
The difference between atoms and ions is that the ion is the same as an atoms that has either gained or lost one or more electrons. Examples: Na is an atom, and it loses 1 electron to become the ion Na+. Cl is an atom, and it gains 1 electron to become the ion Cl-
How many electrons are found in an atom of Na?
there are 11 of them.
Difference between Na and Na plus?
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
How many protons and electrons dose Na plus have?
11 protons and 10 electrons
