How many electrons are found in the outer lever of all the noble gases except helium?
2 electrons are found in the outermost electron shell of Helium. 8 electrons are found in the outermost electron shell of all other noble/inert gases.
How many electrons are there in the third noble gas shell of sodium atom Na atomic number 11?
The sodium atom (Na) has 11 electrons. The electron configuration of sodium is 2-8-1. The third noble gas shell is the second energy level or shell, which can hold a maximum of 8 electrons. Therefore, the number of electrons in the third noble gas shell of sodium is 1.
How many electrons must an iodide ion lose to achieve a noble gas electron structure?
It should actually obtain an electron in order to fill its outer shell.
How many electrons does iodine gain to achieve noble gas electron configuration?
Iodine gains 1 electron to fill it's shell.
How many electrons must a halogen gain to reach stability?
Halogens are in the seventh group on the periodic table, and thus have seven electrons in their outer shell. In order to attain a noble gas configuration, it must gain an electron to form an octet, which is when eight electrons are in the outer shell.

How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.

How many electrons does iodine gain to achieve noble gas electron configuration?
Iodine gains 1 electron to fill it's shell.
How many electrons does silicon have in its outer shell?
4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
How many electrons must a halogen gain to reach stability?
Halogens are in the seventh group on the periodic table, and thus have seven electrons in their outer shell. In order to attain a noble gas configuration, it must gain an electron to form an octet, which is when eight electrons are in the outer shell.
How many atoms are in the last shell of the hydrogen atom?
The hydrogen atom (1H) has only 1 proton and 1 electron (you probably think at this electron).
How many valence electrons do each of the noble gases have. use this information to explian why the noble gases are unreactive?
A noble gas element has as many valence electrons as are needed to completely fill its valence shell: 2 for helium and 8 for all the others. Since a filled valence shell is the condition that other atoms are most likely to reach during chemical reaction, the noble gases are unreactive except with extremely electronegative elements such as fluorine, for which the chemical driving force for gaining an electron to fill the fluorine valence shell is stronger than the energy input required to extract an electron from one of the heavier noble gas atoms.
Lewis dot diagram for helium?
He :The number of electrons in an atom's outer electron shell determines how many dots there are. Helium has 2 electrons in its outer electron shell, so 2 dots.
How many electrons does sulfur have in its third electron shell?
Sulfur has six electrons in its third electron shell.
How many electrons are present in an inert element or noble gases like neon?
1. Neon has 10 electrons; each noble gas has a different number of electrons. 2. The outer electron shell of noble gases is full, containing eight electrons.
