What does the periodic table contain?
The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
Which set of elements make up the reactive group of all metals?
The alkali metals in column 1 of most wide-form periodic tables.
Where do the symbols of the metals come from?
The periodic tables.
Why are periodic tables important in chemistry clasases?
Periodic tables are important in Chemistry classes because they help understand more about protons, electrons, and neutrons of various elements.
What group on the periodic table contains the most nonreactive nonmetals?
The very last group. These have a full set of electrons in their valance shell and will therefore not react easerly. What i mean by very last is the group starting with helium and ending in radon
Where the active nonmetals found on the periodic tables?
the most active is oxygen
Where are the most reactive metals found in the periodic tables?
The alkali metals
How do most periodic tables differentiate between metals and nonmetals?
Metals are present at the extreme left side while non-metals are located at the extreme right side of the periodic table.
What does the periodic table tell you?
The periodic table tells you an element's atomic number and symbol. Also: how many elements that are found right now all the matalloids, metals, and not to mention the nonmetals. Most periodic tables that you see are classified by their properties. The periodic tables tells you how elements are arranged both vertically and horizontally according to their increasing atomic number.
Why is ununoctium on some periodic tables but not others?
Ununoctium was discovered (prepared) in 2006; old Mendeleev tables (printed before 2006) don't contain ununoctium.
What does the periodic table contain?
The four pieces of information in each box of most periodic tables are the element's name, the element's symbol, the element's average atomic weight and the element's atomic number. Other periodic tables have other information, but standard periodic tables almost always have those four.
How many tables are in the periodic table?
The periodic table is just ONE table. There are not sub-tables. The periodic table is divided into periods (the horizontal rows of the table) and groups (the vertical columns). As you move horizontally across the table, an increase is the atomic number is seen, along with trends in acidity, bonding behavior, and reactivity. The groups are arranged to contain elements that have similar properties. For example, Group 1 is called the alkali earth metals group; all are light, highly reactive metals. Many more trends and groupings exist.
Which set of elements make up the reactive group of all metals?
The alkali metals in column 1 of most wide-form periodic tables.
What other numerical value appears in the square for each element on periodic table other than the atomic number?
Almost all "seriously intended" periodic tables also include average Atomic Mass numbers. (Some periodic tables intended for primarily decorative use may not contain any numbers at all.)
Where on the periodic tables are the most reactive metals found?
The 1st column from the left
Where do the symbols of the metals come from?
The periodic tables.
Which is the first element in the periodic tables?
Hydrogen.
