How many electrons are there in o shell?
the O major shell can hold 1 electron
What is the number balance electrons for Group IIA elements?
What is the valance number electrons for Group IIA elements?When you look at the periodic table, you see 8 major columns. This represents the s and p orbitals, which hold 2 and 6 electrons respectively. The elements are placed in a column, based on the number of electrons in the s and p orbital of the outer shell. For example, Mg is in column 2 because it has 2 electrons in the s orbital of the 3rd shell. All elements in column 2 have 2 electrons in the s orbital of their outer shell. The valance number is the charge on an ion of an element. Elements in column 2 do not have a strong attraction for the 2 electrons in their outer shell. An element such as O in column 6 has a stronger attraction for electrons than Magnesium. When an atom of Mg is close enough to atom of O, and a little heat is supplied, the 2 electrons in the outer shell of Mg will move to the outer shell of the O atom giving the O atom 8 electrons in its outer shell, making it very stable.After the 2 electrons in the outer shell of the Mg atom have moved to the outer shell of the O atom, the Mg ion has 2 less electrons in its shells than protons in the nucleus atom. Since protons have a +1 charge and electrons have a -1 charge, the Mg ion has a net charge of +2. The O atom now has 2 more electrons in its outer shell and has a net charge of -2. The charge is the valance number. All atoms of elements in GroupIIa have 2 electrons in the in their outer shell so their valence number is +2.Do a google search for, "magnesium burning", and go to images, and you will see what happens. If you are in a chemistry class, ask your instructor to do this lab.
An element is stable with eight electrons in its?
Oxygen (O) has 8 protons and 8 electrons.
What determines chemical bonding in an element?
Atoms hold their electrons in valence shells, but each shell only holds so many electrons. If an atom's outer valence shell is full, it's inert (does not form bonds). If it's outer shell isn't full, then it will form bonds.
How many electrons are there in 3 shells of O?
There are 8 electrons. 2 in the 1st shell and 6 in the 2nd.
How many outer shell electrons does an oxygen atom have before sharing?
itcarries 8 electrons and 8 protonsand its valency is 2.
How many electrons are there in o shell?
the O major shell can hold 1 electron

An element is stable with eight electrons in its?
Oxygen (O) has 8 protons and 8 electrons.
How O form anion?
Oxygen gains two electrons (is reduced, "Reduction is gain") to form the O2- anion this gives oxygen an outer shell the same as neon, and completes the "octet" in its outermost shell of electrons.
What is the Covalent Bond for Chlorine and Chlorine?
a covalent bond means sharing of electrons the outer most electrons on chlorine shell is 7since chlorine is a diatomic molecule (cl2) it comprises of 2 chlorine atoms having 7in each valence shell. for this molecule to be stable it must attain the stable octet configuration 8electrons in their outer shell x x x Cl x x x x 1 o o o o Cl o o o so they share the electrons (marked with a hyphen) to attain the stable configuration. this sharing of electrons between two chlorine molecules is called sharing of electrons within chlorine
How many electrons does a K shell L shell M shell and N shell o p shell have?
Maximum number of electrons = 2n2, where n is the number of shell (n = 1 for K, 2 for L, 3 for M, and so on) K shell has 2 electrons maximum L shell has 8 electrons maximum M shell has 18 electrons maximum N shell has 32 electrons maximum O shell has 50 electrons maximum P shell has 72 electrons maximum
How do you tell how many electrons are in the outer layer of an element?
The outermost principal shell -or regions around the nucleus where electrons move- contains the valence electrons. The number of valance electrons can be calculated for the columns with A's above them. The number given to the column represents the number of valence electrons (written before and next to the A). For instance, Lithium (Li) and Sodium (Na) have one valence electron because they are in column one. During chemical bonding, these two elements and others in their column have the same configuration of outer electrons; thus, they tend to lose their single electron in order to gain a full outer shell. Similarly, oxygen (O) and sulfur (S) have 6 valence electrons, so they tend to gain electrons to make their full outer shell.
What determines chemical bonding in an element?
Atoms hold their electrons in valence shells, but each shell only holds so many electrons. If an atom's outer valence shell is full, it's inert (does not form bonds). If it's outer shell isn't full, then it will form bonds.
How many electrons are there in 3 shells of O?
There are 8 electrons. 2 in the 1st shell and 6 in the 2nd.
Why is O the element symbol for oxygen?
A lone oxygen atom has 6 outer shell or valence electrons but like other atoms, is most stable with a full outer shell of 8 electrons. In order to get this full outer shell, the oxygen atoms shares electrons with another atom, this is called a covalent bond. In the O2 molecule there are two oxygen atoms bonded together. Each atom contributes 2 electrons to be shared between both atoms, allowing each atom to achieve a full outer shell.
How many electrons does oxygen (O) have in its first electron shell?
O is atomic number 8, so it has 8 protons and 8 electrons. The electron configuration would be1s2 2s2 2p4. So, it has 2 electrons in the first shell (1s2).
