A vertical column in the periodic table. Members of a group typically have similar properties and electron configurations in their outer shell. Period. A horizontal row in the periodic table. The atomic number of each element increases by one, reading from left to right.
circumference - the length of the closed curve of a circle. length - the linear extent in space from one end to the other; the longest dimension of something that is fixed in place; the length of the table was 5 feet. sextant - a unit of angular distance equal to 60 degrees.
The circumference of a circle is the length around the circle which is equal to 360Â°. Pi Î  is the number needed to compute the circumference of the circle. p is equal to 3.14. To find the AREA of a circle, it is equal to 3.14 Î  (p) times the radius (r) to the power of 2.
