Please somebody i need the answer science class is sooo hard
a davb
i guess
some chemical properties of vinegar would be it is transparent flammable but not explosive reactive does not rust so those are just a few but i hope they help.
Calcium fluoride or CaF2 is comprised of two elements: calcium (Ca) and fluoride (F). One molecule of CaF2 thus contains two atoms of F and one of Ca for a total of three.
elements in each group of the periodic table have identical chemical properties as they have the same no. of valence electrons which determines their chemical properties. since calcium is in group II of the periodic table, it has the same chemical properties as the elements in group II. Elements in group II consists of: Be, Mg, Ca, Sr, Ba, Ra Elements in the same group has different physical properties such as boiling and melting points. However there are trends of their physical properties down the group.
The chemical symbol of a nitrogen atom is "N", but at standard temperature and pressure, nitrogen exists primarily as diatomic molecules with the formula N2. Note that all molecules, even those containing only a single type of atom, have formulas rather than symbols, which are properties of atoms or of elements regarded as abstractions only.
blah
who the hell knows... and who honestly cares
Some chemical properties of calcium is that it's highly reactive. I have searched some other chem. properties but all i get is a good conductor, soluble, and an alkaline earth metal. but those are PHYSICAL properties, so I've only found that it's reactive as a chemical property.
The atoms of the reactants are rearranged to form new products that are different in chemical composition and properties from those of the reactants.
atoms in the same group are similar. calcium is in group 2, so it's similar to Be, Mg, Sr, Ba and Ra. Most similar would be Mg or Sr, which are right above and below. all group 2 atoms share a similar electron configuration
Because ions are electrically charged particles that have different chemical properties than their parent atoms. For example, salt is not as dangerous because it contains stable sodium ions, not the reactive sodium atoms of its parent. :)
Recall that atoms also can loan electrons to other atoms so that both can reach a stable energy level. When atoms gain, lose, or share electrons, an attraction forms that pulls the atoms together to form a compound. A compound has different physical and chemical properties from those of the atoms that make up the compound.
The elements that compose it and the arrangement of its atoms

All the properties are different for chemical elements and chemical compounds.
That process is called a chemical reaction.
Because they have gained or lost electrons and are no longer neutral.
