2. PERIODIC TABLE
OF ELEMENTS

3. How to understand more
the periodic table of
elements?

4. THE VERTICAL COLUMNS
OF THE PERIODIC TABLE,
CALLED GROUPS, IN
WHICH IT IDENTIFY THE
PRINCIPAL FAMILIES OF
ELEMENTS.

6. THE HORIZONTAL ROWS
OR PERIODS ARE
NUMBERED FROM THE
TOP TO BOTTOM. THERE
ARE 7 HORIZONTAL ROWS
OR PERIODS IN THE
PERIODIC TABLE.

8. THE ELEMENTS ARE
GROUPED INTO BLOCKS
OR SERIES IN THE
PERIODIC TABLE.

9. Metals, Metalloids

12. LABEL THE ELEMENTS IN THE

14. 1. PERIODIC TABLE IS A
CHART CONTAINING
INFORMATION ABOUT
THE ATOMS THAT MAKE
UP ALL MATTER.

15. 2. THE MODERN
PERIODIC TABLE SHOWS
ELEMENTS ARRANGED IN
ORDER OF INCREASING
ATOMIC MASS.

16. 3. THE MODERN
PERIODIC TABLE IS
DIVIDED INTO GROUPS
OR FAMILIES-
HORIZONTAL COLUMNS
AND PERIODS OR SERIES
– VERTICAL ROWS.

17. 4. EARLY SCIENTISTS
DEVELOPED THE
PERIODIC TABLE BY
ARRANGING ELEMENTS
IN ORDER OF
INCREASING ATOMIC
MASS.

18. 5. SCIENTISTS
DEVELOPED THE
PERIODIC TABLE BY
ARRANGING ELEMENTS
IN ORDER OF
