How does an atom of sodium become more stable?

How does an atom of sodium become more stable?

Forming positive ions A sodium atom has one electron in its outer shell. The atom is more stable if it has a full outer shell. A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons.

Why does an element like sodium give up an electron so easily?

Energy and Ionic Bonds The amount of energy needed depends on the element. Less energy is needed to remove just one or a few valence electrons than many. This explains why sodium and other alkali metals form positive ions so easily. Less energy is also needed to remove electrons from larger atoms in the same group.

Does sodium gain or lose electrons to become stable?

Sodium loses an electron, leaving it with 11 protons, but only 10 electrons. Since it has 1 more proton than electrons, sodium has a charge of +1, making it a positive ion. Chlorine gains an electron, leaving it with 17 protons and 18 electrons.

Why does a sodium atom become more stable when it loses one electron?

Some atoms are more stable when they gain or lose an electron (or possibly two) and form ions. This fills their outermost electron shell and makes them energetically more stable. Because the number of electrons does not equal the number of protons, each ion has a net charge.

Why is sodium ion more stable than sodium atom?

The atom of sodium has one electron in its outermost shell. To achieve a stable electron configuration it has to lose this electron so that all the electron shells are complete. This shows that sodium ions are more stable than the sodium atom, else there would not be a release of heat during the reaction.

How does a sodium atom change into a sodium ion?

A sodium atom has one electron in the outer shell. A chlorine atom seven electrons in the outer shell. A sodium atom loses an electron to a chlorine atom. The sodium atom becomes a positive sodium ion.

Why is an atom of sodium Na happy when it gives up an electron to an atom of chlorine Cl )?

One sodium (Na) atom gives it’s electron to one chlorine (Cl) atom. Chlorine then has the eight electrons in its outer shell to make it “happy”. Sodium is “happy” because it has now given up its one extra electron.

Why does sodium give its electron to chlorine?

Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. It is easiest for sodium to lose its electron and form a +1 ion, and for chlorine to gain an electron, forming a -1 ion.

Would the sodium atom gain or lose electrons to attain Ne gas like electron configuration?

The atomic number of Na is 11. According to the periodic table, the closest noble gas to Sodium is Neon (a noble gas) with an atomic number of 10. Hence, Sodium has to lose only 1 electron to reach the electronic configuration of Neon and by losing that one electron, it becomes a very reactive element.

Why does the sodium atom lose an electron quizlet?

A sodium atom has a total of 11 electrons, including one valence electron and he cam lose an electron to become a positively charged sodium ion. The octet of sodium. When sodium atom lose an electron than is left with an octet electrons which is the same electron configuration of Ne.

When a sodium atom loses an electron it becomes a sodium?

2 Answers By Expert Tutors Sodium will let that electron go as soon as it can, which is why it generally forms ionic compounds such as NaCl. When sodium atom loses an electron from its outer energy shell, it becomes Na+ ion.

Why are sodium ions stable?

question_answer Answers(2) Sodium loses its outermost electrons, when it loses it acquires Octet configuration (eight electrons in outermost shell) so that it gets stability.

Why do metals lose electrons to attain stability?

In the same way sodium loses one electron to attain neon gas configuration. The noble gases will have 8 electrons in the outer shell. If there are no electrons left outside the 8 electrons shell then the atom is said to be stable. So, metals lose electrons to attain stability.

Why are metals more electronegative than non-metals?

If the element is more electronegative, the tendency of it to keep the electrons in it is more. The ionization energy of metals is lower than the ionization energy necessary to take away electron from an atom. Metals tend to give away electrons to form positively charged ions while non metals tend to gain electrons to become negatively charged.

Why is the valency of sodium +1 and lithium +1?

The outer shell has only one electron which can be given away or lost. The remaining configuration is that of a noble gas. So sodium loses one electron and hence it has the valency as +1. In the same way lithium loses one electron to attain the electronic configuration of helium.

Which elements will gain or lose electrons when an ionic compound forms?

Explanation: In general, metals will lose electrons to become a positive cation and nonmetals will gain electrons to become a negative anion. When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons.
