What is true about of all the elements in group 2 on the periodic table?

They all have 2 electrons in their outermost shells, with beryllium(Be) having a electronic structure of 2.2, magnesium(Mg) having 2.8.2, calcium(Ca) having 2.8.8.2 and so on. This means that they have similar chemical reactivity.

∙ 8y agoThey are harder and denser than akali metals. They are not very reactive to water. they have to valence electrons in the valence shell.

∙ 8y agoThey are in the s block. less reactive than 1st group.

∙ 8y agoThat they are metals. They are highly reactive, forming ionic bonds.

Are elements with similar properties found in the same period or group on the periodic table True or False?
Yes. Its true that elements with similar properties are found in same group.
What part of the periodic table doesnt react?
The elements in group 18 are not relatively inert but it is not true to say that they do not react.
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.
The first element on the periodic table of elements is hydrogen?
is it true or false
True or false Au is the symbol for gold on the periodic table of elements?
true
Are elements with similar properties found in the same period or group on the periodic table True or False?
Yes. Its true that elements with similar properties are found in same group.
What part of the periodic table doesnt react?
The elements in group 18 are not relatively inert but it is not true to say that they do not react.
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
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.
True or false Au is the symbol for gold on the periodic table of elements?
true
The first element on the periodic table of elements is hydrogen?
is it true or false
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. ----
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.
Is the position of elements on the Periodic Table is dictated by the number of protons?
true
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 elements in the middle of the periodic table are not able to bond with other elements.?
No. This is not true. Take for example the element sliver (Ag), which is approximately in the "middle" of the periodic table. Such common compounds of Ag, such as AgCl, AgNO3, etc. exist.
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.
