The sodium loses an electron and the chlorine gains an electron. Tell students that when an atom gains or loses an electron, it becomes an ion. 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.If sodium loses an electron, it now has 11 protons, 11 neutrons, and only 10 electrons, leaving it with an overall charge of +1. It is now referred to as a sodium ion.Because the sodium atom has only one valence electron to lose, it tends to form only the 1+ ion. It is a positive ion, because the number of protons (11+) now exceeds the number of electrons (10–).
When sodium loses an electron what does it become?
If sodium loses an electron, it now has 11 protons, 11 neutrons, and only 10 electrons, leaving it with an overall charge of +1. It is now referred to as a sodium ion.
What does a sodium atom become when it loses its only valence electron?
Because the sodium atom has only one valence electron to lose, it tends to form only the 1+ ion. It is a positive ion, because the number of protons (11+) now exceeds the number of electrons (10–).

When a sodium atom loses an electron it becomes a sodium quizlet?
How might this difference be related to the types of compounds formed by atoms of these two elements? When sodium loses it’s electron it becomes a positively charged ion (called a cation), because it has less electrons then protons.
How does sodium become neon?
Sodium would become stable if it could lose an electron and attain the configuration of neon (2,8). Every atom has the tendency to acquire the configuration of the nearest noble gas and become stable.
Is sodium a cation or anion?
Ionic compounds are the combination of cations and anions. In table salt, sodium chloride, sodium is the cation (Na+) and chloride is the anion (Cl–).
How does an atom become ionized?
When one (or more) electron is stripped off or added to the atom, it is no longer electrically neutral and an ion is formed; the atom is said to be ionised. The energy required to ionise an atom can come from collisions or from interacting with electromagnetic radiation (photoionisation).
What ion does sodium turn into and why?
A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1. A positive sign is added to the symbol for sodium, Na +.

what happens when sodium atom loses an electron in its outer …
It reaches the nearest “noble gas” configuration, albeit as the cation Na+. Sodium will let that electron go as soon as it can, which is why it …

the sodium atom becomes a positive ion and the chlorine atom becomes neg.
Ionic Compounds in PHY101
The most common example is sodium chloride, NaCl. In this compound each sodium atom has lost one electron (giving it a charge of 1+) and each chlorine atom has …
What forms after an atom loses electrons?
Explanation: An atom loses electrons to form a cation , that is a positively charged ion (and one that is attracted towards the negatively charged terminal, the cathode ).
What happens to an atom if it loses electron gains electron?
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).
When an atom loses an electron it becomes quizlet?
When an atom loses an electron, it loses a negative charge and becomes a positive ion.

What happens to an atom of sodium when it forms an ionic bond in which it has the same electron configuration as the noble gas neon?
The sodium ion has an electron configuration that is identical to the noble gas neon. When forming a compound, a sodium atom loses its one valence electron and is left with an octet (eight electrons) in what is now its highest occupied energy level.
When a neutral sodium atom loses one electron to form the sodium cation its electron configuration becomes?
The electronic configuration of sodium ion becomes 2,8 on losing one electron. Was this answer helpful?
What does the sodium atom become if it loses a proton from its nucleus?
The nucleus is made up of nucleons – neutrons and protons. An element is defined by the number of protons in the nucleus. If an atom loses or gains a proton, it becomes a new element. For example, if a sodium atom loses a proton, it would become a negative ion of neon.

Can neon become an ion?
The octet of electrons in the neon atom is particularly stable, so we don’t see neon reacting to lose or gain electrons and form ionic bonds.
Does sodium gain or lose electrons?
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.
What ion will sodium form?
The tendency is for sodium to lose an electron so that the new resulting valence shell (2) is in its most stable state (full octet). This loss of an electron results in the ionization of sodium, to form the positively charged ion Na+. FIGURE 3-3.
When an electron is removed from an atom its energy?
Energy is supplied in order to remove electron from an atom, so energy of atom increases when electron is removed from an atom.
When an atom has an electron removed then its net charge is?
Unlike protons, electrons can move from atom to atom. If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.

Is an atom that has lost an electron?
The atom that has lost an electron becomes a positively charged ion (called a cation), while the atom that picks up the extra electron becomes a negatively charged ion (called an anion).
When sodium atoms form sodium ions they what?
A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.
