It is oxygen group elements
Helium only needs two electrons to have a filled outermost energy level.
Selenium needs two more electrons.
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
Yes, selenium needs to gain 2 electrons to achieve an octet configuration because it has 6 valence electrons in its outer shell. By gaining 2 more electrons, selenium can reach a stable electron configuration with 8 electrons in its outermost shell.
Magnesium has 12 electrons, with 2 electrons in its outermost shell. To have a full octet, magnesium needs to lose these 2 electrons to achieve a stable electron configuration, resulting in a 2+ charge as it becomes a cation.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Helium only needs two electrons to have a filled outermost energy level.
Selenium needs two more electrons.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
An atom needs electrons in its outermost shell to be stable. The number of electrons in the outer shell determines the atom's chemical properties and reactivity. If an atom's outer shell is complete, it is considered stable and less likely to react with other atoms.
An atom of oxygen needs to gain 2 electrons in order to complete its outermost energy level and achieve a stable octet configuration. Oxygen has 6 electrons in its outer shell and it can reach a total of 8 electrons, following the octet rule.
It is in Group 7 on the Periodic table which means it already has 7in its outer shell. The shell needs 8 to be complete so fluorine requires 1 more electron which it gains through ionic or covalent bonding.
Yes, selenium needs to gain 2 electrons to achieve an octet configuration because it has 6 valence electrons in its outer shell. By gaining 2 more electrons, selenium can reach a stable electron configuration with 8 electrons in its outermost shell.
To draw the Lewis dot diagram for hydrogen chloride (HCl), you first determine the total number of valence electrons (1 for hydrogen and 7 for chlorine). Place one pair of electrons (representing the bond between the two atoms) and any remaining electrons around the chlorine atom. Hydrogen follows the duet rule so it only needs two electrons around it. This results in a structure with a single bond between hydrogen and chlorine, and both atoms have a full valence shell.
Yes, an element that needs to gain or lose just one or two electrons to achieve a full outermost shell will generally be highly reactive. This is because it only requires a small energy input for these elements to form ions and achieve a stable electron configuration.
In order to determine the number of electrons in the outer orbit/ valence electrons of a metal, first the total number of electrons needs to be determined. This is done by deriving the atomic number from a periodic table. Arrange these in the shell format of 2, 8, 18, 32... The number of electrons in the outermost shell are the valence electrons
