No element can have more than 8 electrons in its outermost shell, as the maximum number of electrons that can occupy the outermost shell is 8 due to the octet rule. Elements may have more than 8 electrons in higher energy levels, but those do not determine the element's chemical properties.
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
Carbon has 4 electrons in its outer shell. To fill its outer shell, carbon needs 4 more electrons to achieve a full valence shell of 8 electrons.
Carbon need to obtain four more electrons in order to obtain a noble gas configuration.
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
Phosphorus has 10 more electrons. A neutral atom of phosphorus has 15 electrons, 3 in the outer 3p shell There are 5 electrons in a neutral atom of boron, 1 in the outer 2p shell.
There are 7 electrons in the outer shell of a chlorine atom. Chlorine belongs to Group 17 of the periodic table, so it has 7 valence electrons.
Elements in Group 1 of the periodic table have one electron in their outer shell, while elements in Group 2 have two electrons in their outer shell. This configuration makes these elements more stable and likely to form ions with a positive charge by losing these outer electrons to achieve a full outer shell.
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
Chlorine has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, which is why chlorine typically gains an electron to form Cl- ion in chemical reactions.
Bromine has 7 electrons in its outer shell, making it part of group 17 on the periodic table. This means it only needs 1 more electron to complete its octet and attain a stable electron configuration. As a halogen, bromine can gain an electron to achieve a full outer shell or share electrons to form compounds.
Carbon has 4 electrons in its outer shell. To fill its outer shell, carbon needs 4 more electrons to achieve a full valence shell of 8 electrons.
an outer valence shell missing one or more electrons. slightly resistive
Each element has shells of electrons and they are limited to how many can be shared in the outer shell. This lets us know what and how many atoms can combine with it. Hydrogen has the need for one electron in its outer shell. Oxygen has the need for two more electrons in its outer shell. Therefore, 2 hydrogen atoms can combine with oxygen.
Chlorine has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, making it highly reactive.
Carbon need to obtain four more electrons in order to obtain a noble gas configuration.
The element with 6 electrons in the outer shell is oxygen. Oxygen has 6 electrons in its outer shell, which is known as the valence shell.
Oxygen has 6 electrons in its outer shell, and it needs 2 more electrons to fill its outer shell, as it follows the octet rule to achieve stability.
