What type of bond would two elements of electronegativity form?
What type of bond would two elements of electronegativity form?
covalent bonds
When two atoms have the same electronegativity the bond between them will be?
Of these, cesium and francium are the least electronegative at values of 0.7. Elements with great differences in electronegativity tend to form ionic bonds. Atoms of elements with similar electronegativity tend to form covalent bonds. (Pure covalent bonds result when two atoms of the same electronegativity bond.)
How does electronegativity relate to bonding?
Electronegativity is a measure of the tendency of an atom to attract electrons (or electron density) towards itself. It determines how the shared electrons are distributed between the two atoms in a bond. The more strongly an atom attracts the electrons in its bonds, the larger its electronegativity.
What is the role of electronegativity in determining the type of between two elements?
How is electronegativity used in determining the ionic or covalent character of the bonding between two elements? Differences in electronegativity are calculated. If the difference is small, the bond is covalent. If the difference is large, the bond is ionic.
How many valence electrons do elements in Group 2 have?
The number of valence electrons
| Periodic table group | Valence Electrons |
|---|---|
| Group 2 (II) (alkaline earth metals) | 2 |
| Groups 3-12 (transition metals) | 2* (The 4s shell is complete and cannot hold any more electrons) |
| Group 13 (III) (boron group) | 3 |
| Group 14 (IV) (carbon group) | 4 |
