Covalent bond
When do covalent bond forms?
When two or more nonmetals share their electrons.
What is a molecule with 2 atoms?
Diatomic molecule
What is the prefix when the number of atoms is 5
Penta-
Check what atoms are in the compound.
Check the prefixes to find the number of atoms. After you check the prefix, write down the number as a subscript on the element’s name.
Why do nonmetals share their electrons?
To achieve the stable electron configuration
What is a polar molecule?
Atoms in the molecule that has a partial positive or negative charge.
What element appears in the name first?
More metallic elements.
What number of subscripts is skipped when you write the formula?
Number 1
What are the two types of covalent bonds?
Polar Covalent Bonds and Nonpolar Covalent Bonds
In C2H4, how much carbon and how much hydrogen are there?
Two Carbon atoms and four hydrogen atoms
Is attraction between polar covalent molecules stronger than the attraction between nonpolar covalent molecules? Yes or no?
Yes
What is the prefix for number 9
Nona-
Which type of covalent bond has a greater attraction between polar and nonpolar covalent bond?
A polar covalent bond has a greater attraction than a nonpolar covalent bond.
which molecules have a higher melting point? Are the polar molecules or nonpolar molecules? Explain.
Polar molecules, because they have greater attraction between the atoms, they need more energy or heat to be melted.
If you have "ao" or "oo" for naming, what do you do?
Convert it into "o"
What is the formula for Oxygen Difluoride?
OF2
Which type of covalent bond has a partial positive charge?
Polar bond
Why do molecules covalently bond?
because the difference between the electronegativities of two atoms in the molecular compound or molecule is too small for an electron transfer to occur to form ions
What is the name of this compound? CP
Carbon Monophospide
What is the formula for Diphosphorus tetroxide?
P₂O₄
