No electrons are reactive. Electrons can, under the huge majority of circumstances, only be removed starting from the outermost, working inwards.
An element with 86 electrons is reactive because it is not a noble gas and does not have a full outer electron shell. Elements tend to react to achieve a stable electron configuration, such as by gaining or losing electrons to achieve a full outer shell.
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
Where there are 8 electrons in the outer shell so a full shell. Elements are reactive when they need to lose or gain an electron. The noble gases are unreactive as they have a full outer shell.
In sodium (Na), which has an atomic number of 11, the electron configuration is 1s² 2s² 2p⁶ 3s¹. This means that the first shell (1s) is filled with 2 electrons, the second shell (2s and 2p) is filled with 8 electrons, and the third shell (3s) contains 1 electron. Electrons fill the shells starting from the lowest energy level (1s) and move to higher levels (2s, 2p, and then 3s) until all 11 electrons are accommodated. Sodium's single valence electron in the 3s shell makes it highly reactive, as it tends to lose that electron easily.
no. electron shells are just what contain the electrons. the inner most shell contains 2, then 8 and so on.
The outermost electron shell in an atom is called the valence shell. It contains the most reactive electrons because these electrons are involved in forming chemical bonds with other atoms.
The outermost electron shell is called the valence shell. It contains the most reactive electrons because these electrons are farthest from the nucleus and are more likely to interact with other atoms to form chemical bonds.
An element with 86 electrons is reactive because it is not a noble gas and does not have a full outer electron shell. Elements tend to react to achieve a stable electron configuration, such as by gaining or losing electrons to achieve a full outer shell.
The overall of an atom is a nucleus (protons and neutrons), and 1 or 2 electrons. The rest are for large atoms: an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons, an electron shell, electrons.
An octet of electrons is when the outermost electron shell of an atom contains eight electrons.
Where there are 8 electrons in the outer shell so a full shell. Elements are reactive when they need to lose or gain an electron. The noble gases are unreactive as they have a full outer shell.
When full, the innermost electron shell of an atom contains 2 electrons, and the outermost shell contains 8 electrons. This is known as the octet rule, where atoms tend to gain, lose, or share electrons in order to achieve a full outer shell of 8 electrons.
The outer most electron shell of iodine atom contains 7 electrons.
Sulfur has six electrons in its third electron shell.
Atoms can be reactive if they have an incomplete outer electron shell. This can result in the atom either gaining, losing, or sharing electrons with other atoms to achieve a stable electron configuration. Some common reactive atoms include those from the halogen and alkali metal groups.
The first shell can have 2 electrons, the second shell has 8 electrons and the third shell has 8 electron also. No matter what, electron fill up the first shell and then move into the next shell and then the next one. To answer the question, the first shell would have 2 electron and then the second shell would have six.
It have an electron configuration of 2,8,8,SO it contains 8 electrons in it's outer shell.
