What is needed for electrons to pull away from atoms?
you need two atoms depending how many electrons they want to get or get rid of like water hydrogen wants to give away one electron and oxygen wants to get two electrons that is how it becomes H2O
Atoms with 1 or 2 electrons on their valence level tend to gain?
more electrons because all atoms want to be like noble gases and will either give or take electrons to obtain 8 electrons so atoms with either 1 or 2 electrons would wither give off 1 or 2 electrons depending on how many then had
What type of ion is produced by the gaining of electrons?
When the valence (outer) shell has 5 or more electrons, excluding 8, including hydrogen, being more reactive when there are more electrons. This is because the atom wants to have 8 electrons in its outer shell (hydrogen wants 2), so those with 8 electrons don't want to react, while those with 7 REALLY want to react.
When you draw the Lewis structure for Cl how many odd electrons are there in this atom?
Cl has 7 electrons. If you draw Cl^-, there are 8 electrons and a minus 1 charge. What do you want to draw? And what do you mean by "odd" electrons?
How many electrons does the first shell of a atom contain?
First shell contains atmost two electrons. The formula is 2n. where n is the no. of shell u want to calculate its capacity of no of electrons..thanku

How many electrons does hyrdogen want?
It wants one.
Do all atoms want 8 electrons?
No, Hydrogen, Lithium and Beryllium tend to complete 2 electrons in outermost shell and most of the Transition metals tend to complete 18 electrons and other 8 electrons.
What are valence electrons and why are they important in forming compounds?
Valence electrons are electrons in the outermost shell. If the shell is not completely filled, then it tends to "want" to be filled, and those electrons can share positions between atoms. This is called a covalent bond, and it can be very powerful, causing various molecules to form in preference to others. For instance, water is formed from the covalent bond of two atoms of hydrogen and one atom of oxygen. The two atoms of hydrogen have one electron in a shell that "wants" to have two, while the atom of oxygen has 6 electrons in a shell that "wants" to have 8. The two hydrogen electrons fill in the oxygen shell, and two other electrons from oxygen fill in the two hydrogen shells.
Why dont hydrogen and oxygen atoms share electrons equally in a water molecule?
Because the electronegativity of oxygen is about 3.5 and the electronegativity of hydrogen is about 2.5. So, the electrons shared in this polar covalent bond spend more time in the orbitals around oxygen that the orbitals around hydrogen giving the molecule slightly negative and positive ends.
Transferring or sharing electrons between atoms form?
Covalent bonds are formed when atoms share electrons. Let's take hydrogen for example. To be the most "happy" atoms want their outermost orbital full of electrons. Hydrogen has only one electron in its 1s orbital, but the 1s orbital can hold two electrons. Hydrogen wants two electrons to be "happy" so it will do what it takes to get them. If a hydrogen atom bumps into another hydrogen atom they can both become "happy" as each atom will share its electron with the other atom, giving each a full outermost orbital with the help of the other atom's electron. This is what creates the bond in covalent bond as the hydrogen atoms are "happier" together with a full orbital than they would be with a half-full orbital apart.
Why is hydrogen electropositive?
Because it has only one electron in its valence shell. Its valence shell holds two electrons so it really wants to share its electron to make a bond of two electrons two fill its valence shell. Thus it is the mose "electron-donating" element. Electronegative elements want electrons so hydrogen donates its electron thus hydrogen is electopositive.
Electrons that participate in chemical bonding are typically located closest to the nucleus?
No. It depends what the atom is, first of all, because different atoms have different numbers of orbits and subshells. In general, electrons want to go to a higher state (further away from the nucleus) but then they fall. The outside electrons are the ones that want to share bonds. Look up VSPER/electron configuration. I don't know how to explain it well enough, but I know how to read it. H:H -Hydrogen shares electrons with another Hydrogen atom. Hydrogen has 1 electron- H. ) the dot is the electron which should be written to the right of H and in the middle. H.) your other hydrogen. So now it looks like H:H (correctly drawn). The Hydrogens are sharing electrons in their bonds. This is why it depends on the atoms, because they have a different number of electrons that they may share. Look that up! It'll help-or at least tell you how many electrons there are for each atom.
How many electrons does an atom want in its valence shell?
8
What type of ion is produced by the gaining of electrons?
When the valence (outer) shell has 5 or more electrons, excluding 8, including hydrogen, being more reactive when there are more electrons. This is because the atom wants to have 8 electrons in its outer shell (hydrogen wants 2), so those with 8 electrons don't want to react, while those with 7 REALLY want to react.
How many partners does hydrogen want to have?
It wants just one partner.
