Writing Formulas of Ionic Compounds
The formulas are written as follows:
Positive ionxNegative iony
where x and y are subscripts indicating the combining ratio of
positive and negative ions. If a subscript is one, it is not
written. The combining ratio is
Metals Forming More Than One Ion
In the previous material, the charges on the ions made from
metals were based on the losing of electrons to attain the electronic
configuration of a noble gas. Not all metals do this. They do lose
electrons, but will not h
MEASURING PHYSICAL PROPERTIES
Chemistry is the study of the composition and structure of
matter and the changes that matter undergoes. Matter is anything
that occupies space and has mass. Mass is a measure of the
quantity of matter. The weigh
ATOMS AND ELEMENTS
An atom can be defined as the smallest unit of an element that
can take part in a chemical reaction.
Three subatomic particles used
to make up atoms are protons, electrons, and neutrons.
A proton carries a one-unit positive charge, an e
Dimensional analysis is used for converting a unit to
another unit. To use this mathematical procedure, you have to
know the relationship between the units. The question of how
