ODYSSEY: DESIGNING AND ORGANIZATIONAL MAP: THE PERIODIC TABLE
How many electrons will a non-metal generally have in its outer shell?
4-7
How many electrons can the 5th shell hold?
50
The element gold occurs in which period?
6TH
How many valence electrons does chlorine have?
7
Which element in Group IIA will have the highest melting temperature?
BE
The last element in any period always has
EIGHT ELECTRONS IN THE OUTERMOST ENERGY LEVEL. THE PROPERTIES OF A NOBLE GAS.
another name for group
FAMILY
A vertical column within the periodic table represents a family or
GROUP
the vertical column of the periodic table
GROUP
Which element is NOT in the cobalt subgroup?
IRON
Which elements are included in Group 5A?
N,P,BI
Which of the following elements is a transition metal?
NICKEL
Select all that apply to the organization of the periodic table
THE PERIODIC TABLE IS ARRANGED IN ORDER OF INCREASING ATOMIC NUMBER. PROPERTIES OF ELEMENTS CAN BE PREDICTED FROM THEIR PLACEMENT ON THE TABLE. A HORIZONTAL ROW IS CALLED A PERIOD. A VERTICAL COLUMN IS CALLED A GROUP.
What is common about the elements of a period?
THEY HAVE THE SAME NUMBER OF ELECTRON ENERGY LEVELS. THEY TRANSITION FROM METAL TO NOBLE GAS.
Which statements are correct about a Group?
The elements in each group have similar chemical properties. Each member of the group has the identical electron configuration in the outer shell.
an atom will gain, lose or share electrons in order to obtain eight valence electrons
OCTET RULE
A horizontal row of elements in the periodic table is known as a
PERIOD
the horizontal row in the periodic table
PERIOD
What law states that the physical and chemical properties of the elements are periodic within the sequence of their atomic numbers?
PERIODIC LAW
a table of the elements, arranged to illustrate the periodic characteristics of the elements
PERIODIC TABLE
Which is the first element in the periodic table to have an electron configuration in the 4th energy level?
POTASSIUM
What is a common characteristic of the transitions elements?
THE NEXT TO OUTERMOST ELECTRON SHELL BEGINS TO FILL UP.
Why do the chemical properties cycle through each period?
The outermost shell of all atoms with two or more electron shells will not have more than 8 electrons.
electrons in the outermost energy level of an atom
VALENCE ELECTRON
