How many shells does oxygen have?
2
Number of valence electrons in two hydrogen atoms?
Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two valence electrons :)
Can hydrogen fill it's outside shells with two electrons?
Yes, hydrogen can fill its outer shell with two electrons. Hydrogen has one electron in its first shell, so by gaining one more electron it can achieve a stable configuration with two electrons in its outer shell.
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
What two atoms follow the duet rule in filling up their valence shells of electrons?
Hydrogen and helium follow the duet rule, which means they strive to have a full valence shell with two electrons. Hydrogen can achieve this by gaining one electron, while helium already has a full valence shell with two electrons.
How many number of full shells do chlorine-35 have?
Chlorine-35 has three full shells of electrons. It has two electrons in the first energy level, eight electrons in the second energy level, and seven electrons in the third energy level, making a total of 17 electrons.
How many outer shells are there in magnesium?
Magnesium has 3 outer electron shells. It has 12 electrons with 2 in the first shell, 8 in the second shell, and 2 in the third shell.
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 does the outer shells of two atoms that are covalently bonded?
In a covalently bonded molecule, atoms are bonded by the sharing of their electrons. When Oxygen combines with two Hydrogen, H2O is formed by two covalent bonds. Oxygen, which has 6 outer electrons, needs to gain two electrons to form a completely stable octet of electrons. Each of the Hydrogen atoms requires a single electron to complete its outer level of electrons. The resulting molecule is a angularly bonded molecule of water with two double covalent bonds: O <- oxygen shares 1 electron with each hydrogen atom // \\ <-double covalent bond H H They overlap
How many outer shells does beryllium have?
Beryllium has one outer electron shell with two electrons.
How is a molecule of hydrogen form from two hydrogen atoms?
Well with any element when two atoms are put together they are known as a molecule of that element. So one atom of hydrogen is known as one atom of hydrogen and two atoms of hydrogen is known as one molecule of hydrogen.
How many shells does berkelium have?
Berkelium has 97 electrons, which means it has 7 electron shells.
