How many electrons does hydrogen need in order to have a full shell of valence electrons?
1. two
2. an atom wants a full outer shell of valence electrons, so it will either transfer or share electrons depending on what the other atom needs
3. O=C=O
4. No, there is not because carbon needs four bonds, so it bonds with each
5. H-O-O-H

Well, hydrogen is like that one friend who prefers to have only one electron in its valence shell. It's a bit of a loner, you know? So, hydrogen just needs one electron to be happy. It doesn't want any more, and it definitely doesn't want to share. One is enough!
To find out how many electrons hydrogen needs to have a full shell of valence electrons, we need to understand the electron configuration of hydrogen.
Hydrogen is the first element in the periodic table and has atomic number 1. Its electron configuration is simply 1s¹, meaning it has one electron in its 1s orbital.
To have a full shell of valence electrons, hydrogen needs 2 electrons. This is because the first shell (n=1) can only hold a maximum of 2 electrons. Since hydrogen has only one electron, it needs another electron to fill its valence shell.
However, it's important to note that hydrogen rarely achieves a full shell of valence electrons. Instead, it typically forms a covalent bond with another atom to share electrons and reach a stable electron configuration.
