They are called bridge elements because the 'bridge' the first two elements with only one electron shell to the rest of the Periodic Table, which have ascending amounts of electron shells. The first two are also the most abundant elements in the universe.
What else can I help you with?
Why Na Mg are bridge elements?
NA and MG are bridge elements because some of the second period elements show a diagonal relationship with the third period elements. Other examples would be LI and MG.
Elements of group of 2 are called?
The elements of the second group are called the Alkaline Earth metals.
Period in chemistry?
A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
Why do element in the third period have lower ionization energies than elements in the second period?
With each additional period, there is an additional energy level, which means that the outermost electrons are farther away from the nucleus of the atom. This means that the attractive force of the positively charged nucleus is less, so it takes less energy to remove an electron from an atom in the third energy level than it does from an atom in the second energy level. Therefore, the elements in the third period have lower ionization energies than elements in the second period.
What are the first three periods of the periodic table called?
The first three periods of the periodic table are called the first period, second period, and third period.
Why Na Mg are bridge elements?
NA and MG are bridge elements because some of the second period elements show a diagonal relationship with the third period elements. Other examples would be LI and MG.
Why sodium and magnesium are called bridge elements?
Because some of the second period elements show a diagonal relationship with the elements of third elements in showing a similar kind of propertiesLi and Mg show diagonal relationship Be and Al also and many more
What is the second period on the periodic table called?
Second period elements have two electronic shell.It comprises of eight elements.They are lithium,beryllium,boron,carbon,nitrogen,oxygen,fluorine and neon.
What are the elements in the second period of the periodic table of elements?
You can discover this by looking at a periodic table of the elements.The rows of the table are called periods; the columns are called groups.The second period therefore begins with the element Lithium and ends with the element Neon.
What is second period at the bottom of the periodic table called?
The first period is at the top of the table. It consists of hydrogen and helium. The bottom period is period 7.
An element in the second row of the rare earth elements in the periodic table are?
litium, and elements in the 2nd period (row) are pretty common
How many elements occur in each of the first three periods or the periodic table?
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
What group of elements in the periodic table is made up of elements that are gases at room temperature?
The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.
How many elements are there in the second period of the periodic table?
Eight. In order as would be seen in the second period on the periodic table, they are Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), and Neon (Ne).
Which elemets are in the second period?
The elements in the second period are lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon.
What are the last two lines on the periodic table called?
They are called f-block elements. The first row elements are called lanthanides. The second row elements are called actinides.
How many electron shells do the atoms of elements in the second period have?
two K and L
