All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
There are 7 outer orbital electrons in an atom of chlorine, as it has 7 electrons in its outermost energy level.
Xenon is found in group 18. It has an electronic configuration of 2, 8, 18, 18, 8 and has eight valence electrons (or eight electrons in the outer most orbital).
A neutral sodium atom has 11 electrons. In its outer energy level, it has 1 electron. Sodium's electron configuration is 2-8-1.
An atom of phosphorus (P) has five outer orbital electrons in its third energy level, as it has 15 electrons in total with electronic configuration 2-8-5.
When a typical atom's outer orbital is filled, it will have 8 electrons, except for helium which will have 2 electrons. This is because the outer orbital, known as the valence shell, can hold a maximum of 8 electrons.
Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
There are 7 outer orbital electrons in an atom of chlorine, as it has 7 electrons in its outermost energy level.
Xenon is found in group 18. It has an electronic configuration of 2, 8, 18, 18, 8 and has eight valence electrons (or eight electrons in the outer most orbital).
It needs to lose one electron so that it can have 8 electrons in its outer orbital
Valence electrons are electrons found in the outer orbital (shell of an atom) They are the electrons used for bonding
A neutral sodium atom has 11 electrons. In its outer energy level, it has 1 electron. Sodium's electron configuration is 2-8-1.
An atom of phosphorus (P) has five outer orbital electrons in its third energy level, as it has 15 electrons in total with electronic configuration 2-8-5.
When a typical atom's outer orbital is filled, it will have 8 electrons, except for helium which will have 2 electrons. This is because the outer orbital, known as the valence shell, can hold a maximum of 8 electrons.
The elements which falls under the group 16 has 4 electrons in its outer p orbital...
Two electrons in the outer shell of radium.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
The outer orbital, or valence shell, around the nucleus of an atom possess what are commonly called valence shell electrons. They represent the electrons available to share with another atom for the formation of covalent bonds between atoms. For Na, or sodium, in its standard atomic state there is only 1 valence shell electron. This number increases as you go to the right across the periodic table until the number of valence shell electrons reaches 8. This is noted by the Column number (i.e. I, II, III, etc.). Carbon has four, Nitrogen has five, Oxygen has 6, and Fluorine has 7. Xenon, Argon and the other 8th column elements are called the noble gases and they all have 8 valence electrons.
