gain 2 electrons
If you go to your preferred search engine and search for "lewis dot of Se" you will find it. This is the best I can make on this form....Se:.
The selenium atom shown below has 2 extra electrons, so it would likely bond with an atom that needs 2 electrons to fill its outer shell. For example, selenium could form a stable ionic compound by bonding with an atom like oxygen, which has a tendency to gain 2 electrons to achieve a full outer shell configuration.
S2 molecule has a double bond because each sulfur atom contributes two valence electrons and they share two electrons to form a covalent bond. This allows each sulfur atom to achieve a stable octet configuration and satisfy the octet rule.
A hydrogen atom can form a covalent bond without fulfilling the octet rule because it only needs two electrons to achieve a stable electron configuration, which is a duet rule for hydrogen. This allows hydrogen to share electrons with another atom to complete its valence shell and achieve a more stable state.
Xenon can achieve a stable octet by forming compounds with elements that can share their electrons with xenon. For example, xenon can form compounds with fluorine, chlorine, or oxygen where xenon acts as the central atom and bonds with these more electronegative elements to complete its octet.
An atom of selenium will gain two electrons to form an octet in its valence shell. This will allow it to achieve a stable electron configuration similar to a noble gas.
Yes it will. Selenium has 6 valence electrons. If it accepts two more electrons to form Se2-, the resulting ion will have octet of electrons in the valence shell and will be stable.
Each hydrogen can form one bond with selenium. Each selenium atom can form two bonds, one with each hydrogen (2 hydrogen atoms total).
No, xenon does not always follow the octet rule. It is a noble gas and can form stable compounds that have more than eight electrons around the xenon atom, known as expanded octet.

An atom becomes charged when it gains or loses electrons to form an octet.

Hope fully some won will get the awnser but i dont no so i am guessing if you get to blue burry muffins from dockin doughnuts and merge them together to create a whole different elemtal bon that be awsome. Remember only BLUEBERRY da da :) :) :)
One.
Chlorine is the most active nonmetal out of argon, chlorine, potassium, and selenium. It belongs to the halogen group, which is known for its high reactivity. Chlorine readily reacts with other elements to form compounds.
