Water
Two examples are nitrogen (N2) and oxygen (O2).
A polar compound is a molecule that has a slight positive and negative charge due to differences in electronegativity between its atoms. This results in an uneven distribution of electrons within the molecule. An example of a polar compound is water (H2O).
The phosphate groups in the DNA molecule give it a negative charge.

To write the formula for a covalent compound, you would use the prefixes that indicate the number of atoms of each element present in the molecule. For example, nitrogen dioxide is written as NO2, where "mono" is not used for the first element. An example of a covalent compound is methane (CH4), where one carbon atom is bonded to four hydrogen atoms through covalent bonds.
Being a teacher's aide at a local elementary after-school program would give you a good chance at gaining experience in the field.
Take a poll and see how many people recycle is an example of an investigatory projects for elementary students. You could also compare statistics of your state vs other states to see who recycles more.
elementary means simple or basic: "The concept of multiplication was elementary to the college math majors."
A molecule is the smallest unit of most chemical compounds. Scientists use a kind of shorthand called a chemical formula that shows the type and number of elements in a molecule. For example, a water molecule is written as H2O, which means there are 2 atoms of Hydrogen and 1 atom of Oxygen.
ATP
Subscripts give you the number of molecules in that compound. (For example, H2O contains one molecule of Hydrogen.) Superscripts give you a charge.Read more: If_a_formula_for_compound_what_do_the_numbers_tell_you
NO molecule has 15 (odd) electrons, 8 from oxygen and 7 from nitrogen.
I not speak your language O.e
Water (H2O) is an example of a compound, as it is made up of two different elements, hydrogen and oxygen, chemically bonded together. Oxygen gas (O2) is an example of a molecule that is not a compound, as it consists of two atoms of the same element bonded together.
