What happens when magnesium atom loses electron in its outer energy cell?
2 Answers. The magnesium ion Mg2+ is formed when the magnesium atom loses the two electrons from its outer shell! to form a stable ion with a noble gas configuration.
What happens when an atom loses an electron in its outer energy shell?
Atoms that lose electrons acquire a positive charge as a result because they are left with fewer negatively charged electrons to balance the positive charges of the protons in the nucleus. Positively charged ions are called cations. Most metals become cations when they make ionic compounds.

| 8 A magnesium atom that loses two electrons becomes a (1) positive ion with a smaller radius (2) negative ion with a smaller radius (3) positive ion with a larger radius (4) negative ion with a larger radius | 1 |
When magnesium loses all the electrons in its outer shell What is its overall charge?
+2
Magnesium has two electrons in its outer shell as it is in group 2 of the periodic table, which it loses, so its outer shell is full (2,8) and it has a charge of +2, as it still has 12 protons (positive charges) and now has only 10 electrons (negative charges).
Is sodium atom that has lost an electron comes near a chlorine atom that has gained an electron what happens?
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.
How does magnesium become stable?
To form a stable ion, magnesium will lose two electrons. This empties its valence shell, giving it an electron configuration identical to its…
What happens when the sodium atom loses electrons?
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. Chlorine (Cl) in its lowest energy state (called the ground state) has seven electrons in its outer shell.
When a chlorine atom gains an electron what does it become?
Similarly, if a chlorine atom gains an extra electron, it becomes the chloride ion, Cl–. Both ions form because the ion is more stable than the atom due to the octet rule.
What are the two most stable ions magnesium can make?
Which is more stable magnesium atom or magnesium ion? Mg is more stable because it is neutral atom while Mg^+2 to be stable will loses two electrons readily.
What must magnesium do to become stable?
In order to achieve noble gas configurations, the magnesium atom needs to lose its two valence electrons, while the bromine atom, which has 7 valence electrons, requires one additional electron to fill its outer shell.
When a sodium atom loses an electron what does it become?
2 Answers By Expert Tutors. 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 generally forms ionic compounds such as NaCl. When sodium atom loses an electron from its outer energy shell, it becomes Na+ ion.
Why does a sodium atom become more stable when it loses one electron?
Why does a sodium atom become more stable when it loses one valence electron? the sodium atom becomes a positive ion and the chlorine atom becomes neg.
