Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals can gain electrons to fill their valence shells. By doing so, they can achieve a stable electron configuration, usually by reaching a full outer shell of electrons (usually 8 electrons, except for hydrogen and helium which only need 2 electrons).
How many electrons are needed to fill valence shell in hydrogen?
The atomic number for hydrogen (H) is 1 in the Periodic Table of Elements and it has that number of electrons (Valence & otherwise). Hence H2O for water since Oxygen O needs 2 electrons added to its valence electrons to make the stable compound WATER.
How are electrons arranged in the atom?
Electrons are arranged in energy levels or shells around the nucleus of an atom. The first shell can hold up to 2 electrons, while the second and third shells can hold up to 8 electrons each. The electrons fill up the shells in order of increasing energy levels.
How many energy levels would electrons of hydrogen and helium fill?
Electrons of hydrogen fill up to two energy levels, while electrons of helium fill up to a total of two energy levels as well. Helium has an additional energy level compared to hydrogen because it has 2 electrons, filling up both the first and second energy level.
Why does oxygen have two shells?
Oxygen has two electron shells because it has eight electrons in total, with two in the first shell and six in the second shell. Atoms tend to fill their outermost electron shell to achieve stability, and oxygen does this by sharing electrons with other atoms or gaining electrons to fill its outer shell.
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals can gain electrons to fill their valence shells. By doing so, they can achieve a stable electron configuration, usually by reaching a full outer shell of electrons (usually 8 electrons, except for hydrogen and helium which only need 2 electrons).
How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
Does the electrons go on the shells?
Yes electrons go on shells , that's the way the are organize . The more shells they fill the greater their atomic number .

How many electrons in hydrogen valence shell will give it a noble gas configuration?
Two electrons will fill a hydrogen's outer, or valence, shell.
16 electrons need how many shells?
16 electrons would fill up the first four shells in an atom: 2 electrons in the first shell, 8 electrons in the second shell, 4 electrons in the third shell, and 2 electrons in the fourth shell.
How many energy levels would electrons of hydrogen and helium fill?
Electrons of hydrogen fill up to two energy levels, while electrons of helium fill up to a total of two energy levels as well. Helium has an additional energy level compared to hydrogen because it has 2 electrons, filling up both the first and second energy level.
Why does oxygen have two shells?
Oxygen has two electron shells because it has eight electrons in total, with two in the first shell and six in the second shell. Atoms tend to fill their outermost electron shell to achieve stability, and oxygen does this by sharing electrons with other atoms or gaining electrons to fill its outer shell.
How man electrons would you need to fill the outermost ring of hydrogen?
1: The outermost ring of hydrogen is the s-level, which can contain only two electrons, and a hydrogen atom itself already has one of these electrons.
How many electrons would you need to fill the outermost ring of hydrogen?
Hydrogen need 1 more electron to fill outermost orbit. Then, H will act as anion.
How many electrons would hydrogen require to fill up the first shell?
hydrogen has only one shell and since it has atomic number one, its net number of electrons is one. the first shell can hold maximum of 2 electrons due to the bohr bury formula. so the number of electrons in its first shell is 1. to fill it 1 electrons are required which can be gained from any metal.
