What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.
How is each element placed in the periodic table?
Elements are arranged into rows in order of increasing mass, so that elements with similar properties were in the same column. They are organized by type, such as nonmetals, metals, and metalloids, and solids, liquid, gas, or not found in nature.
What trend in atomic radius do you see as you go down a group on the periodic?
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
Why zero group elements are mono atomic?
Atoms of these elements do not combine with other atoms, even atoms of the same element, because their valence electron shells are full.
How the properties of element repeat after regular intervals?
According to the Modern Periodic Law, the properties of the elements are repeated after certain regular intervals when these elements are arranged in order of their increasing atomic numbers. Further an examination of the electronic configuration of the various elements clearly indicates that with a gradual increase in atomic number there occurs a repetition of similar outer electronic configurations after certain regular intervals. By correlating these two observations, we can say that, the cause of periodicity in properties is the repetition of similar outer electronic configurations at certain regular intervals. When we go across the period the no. of shells remains same but the number of electrons keep increasing .this result in more force of attraction among electrons and protons and thus atomic size decreases. But when we go down the group, the no. of valence electrons remains same but the no. of shells keep increasing.this result in less force of attraction. Therefore, atomic size increases.
Which other elements contain the same number of atomic shells as sodium written as the chemical symbols?
The elements of period 3 has same number of shells as sodium. These elements are Mg, Al , Si, P , S, Cl and Ar.
What happens to the atomic radii of the elements as a group is descended?
As we descend down the group, the atomic radii increases. This is because the number of shells increases.
Which determine the chemical properties of an element?
the atomic masses and atomic numbers... group number and period number... valence electrons and number of shells... these all determine the chemical properties of elements...
What are elements of a group that has the same number of shells?
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
The rows going across the periodic table is known as periods and contain elements with the same number of?
Electron shells
How does the size of elements vary down the group in the periodic table?
Atomic size increases down the group. The number of shells increases causing more atomic radius.
What element has the same number of atomic shells as sodium?
All of the elements in the same period (row) of the periodic table as sodium have this property.
What characteristics must two elements share if they are in the same period?
The same number of electron shells,thus similar atomic structure.
How are elements are arranged on periodic table?
Dmitri Mendeleev and Lothar Meyer first arranged the elements in the increasing order of atomic masses. Bohr and Henry Moseley then arranged the elements in the increasing order of atomic number.
What do the elements in the periodic table have?
Elements in the same column have the same number of valence electrons, and form ions with the same charge.
How many electrons are all atoms trying to get?
atoms try to get 10 electrons on shells around the atom. how many shells the atom has is based on the atomic number and atomic mass the atomic number determines how many shells their are.
Why do elements increase in size as you move down the periodic table?
Down the group, atomic radius increases. This is due to increase in number of shells.
