Is the position of elements on the Periodic Table is dictated by the number of protons?
true
True or False The chemical reactivity of metals tends to increase from left to right across the periodic table?
False. The most chemically reactive metals are in the two leftmost columns.
A period is a horizontal on the periodic table true or false?
Yes!The elements are arranged in horizontal rows and vertical columns to represent what is called the periods on the periodic table.
What is true about elements in the same period of the periodic table?
If they are placed in the same vertical column, which is called a group, it means that they have similar properties. For example, the first column (group) of the periodic table are the alkali metals. The second is alkali earth metals. Other groups include halogens, royal gases, etc.
Is it true or false that the periodic table is divided into rows or columns?
It is true that periodic table is divided into rows and columns. The rows are called periods and columns are called groups.
Are there more metalic elements or nonmetalic elements listed on the periodic table?
There are more metals than nonmetals on the periodic table. There are 18 nonmetals, compared to 117 known elements.
Is it true that transition metals are less reactive than the metals in group one and two of the periodic table?
True
Is the position of elements on the Periodic Table is dictated by the number of protons?
true
Which are more common metals or nonmetals?
Metal because there the biggest section of elements on the periodic table true statement.
Is it true that elements on the left side of the periodic table tend to bond with elements on the right side?
It is true that elements on the left side of the periodic table tend to bond with elements on the right side of the table. Those on the left are called metals, and those on the right are called non metals, and a metal plus a non metal form an ionic bond. An example might be Na and Cl to make NaCl.
True or False The chemical reactivity of metals tends to increase from left to right across the periodic table?
False. The most chemically reactive metals are in the two leftmost columns.
Is it true the most chemically reactive metals are in group 1 of the periodic table?
yes the most chemically reactive elements are in group 1
A period is a horizontal on the periodic table true or false?
Yes!The elements are arranged in horizontal rows and vertical columns to represent what is called the periods on the periodic table.
Why are most of the elements on the left and middle of the periodic table metals?
Most of the metals in the left and middle are metals.They have tendency to donate electrons and acquire stable state.
Elements are organized in the periodic table by their?
The periodic table is a function of the atomic number.
Is it true or false that Mendeleev and other scientists were able to use the periodic table to predict the properties of undiscovered elements?
yes it is true. that is how the periodic table was established. ----
Is it true there are 7 groups or rows in the periodic table?
There are 18 groups that make up The Periodic Table of Elements.
