the electrons are shared equally between two atoms because they need eight electrons on the valence(last) shell so that the elements can reach a state of stability. The idea here is to have the elements have the same amount of electrons on the last shell as those in the noble gas group.
Let's consider covalent vs. ionic bonds to see what the difference is. We say a bond is ionic when electrons spend much more time around the more electronegative element. That is, we classify the bond type based on the electronegativities of the participating elements (Electronegativity is a measurement of an element's ability to 'steal' electrons). We say that a bond is ionic when the difference in electronegativities is around 0.5 or more.
ENhigh - ENlow > 0.5 ----- Ionic bond
ENhigh - ENlow < 0.5 ----- Covalent Bond
Sodium has EN = 0.9. Chlorine has EN = 3.0
3.0 - 0.9 = 2.1, NaCl is an ionic bond
Carbon has EN = 2.5. Hydrogen has EN = 2.1
2.5 - 2.1 = 0.4, CH4 has covalent bonds
To share electrons equally, two atoms should have the same electronegativity.
If the atoms in a covalent bond share electrons equally, the bond is nonpolar.
the two atoms must be of the same element
A covalent bond occurs when atoms are sharing electrons equally.
Valence shell electrons or valence electrons determine the chemical properties of an atom...
Ions are atoms that have a postive or negative charge because they have loss or gained negative particles (electons).
If the atoms in a covalent bond share electrons equally, the bond is nonpolar.
A covalent bond.
the two atoms must be of the same element
the two atoms must be of the same element
a type of strong chemical in which two atoms share one or more pairs of valence electons
A covalent bond occurs when atoms are sharing electrons equally.
It's covalent bonding ((:
Valence shell electrons or valence electrons determine the chemical properties of an atom...
Yes, atoms are made up of Neutrons, protons, and electons.
Ions are atoms that have a postive or negative charge because they have loss or gained negative particles (electons).
A covalent bond is formed.
