Why is Hydrogen in group one of the periodic table?
Because it contains just one proton in its 'Nucleus'.
What are the general properties of the elements in the group on the right side of the periodic table?
The elements present at right side groups of the periodic table are non-metals. They have high electron affinity and ionization energy.
What trend in atomic radius occurs going down on the periodic table and why?
Atomic radii increases moving down a group in the Periodic Table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus.
Symbol for sodium on periodic tables?
Symbol for sodium is Na. It is group-1 element.
What is the number of valence electron for all the elements in periodic table group 1A 1?
One valence electron.
How does the ionisation energy change down the groups in the periodic table?
Ionisation energy decreases down the group. It is easy to remove an electron.
What is ionization energy and how does it relate to the periodic table?
The ionization energy is the energy needed to extract an electron from an atom.The value of the ionization energy increase from left to right in a period of the periodic table and decrease in a group from the above to down.
Which group in the periodic tables has 7 valence electrons?
group 17, halogens
What trend in atomic radius occurs down a group in the periodic table?
Atomic radii increases moving down a group in the Periodic Table due to the increasing energy levels in the electron configuration and electrons filling in energy levels further away from the nucleus.
How would you find valence electrons in a periodic table?
the group number of the periodic table shows the valence electron. such as :- sodium is placed in group 1 and have valence electron.
Which group on the periodic table will gain an electron in reaction?
group 17 - the halogens
Which group in the periodic table loss electron?
Alkali metals, Ist group.
Why is Hydrogen in group one of the periodic table?
Because it contains just one proton in its 'Nucleus'.
What group in the periodic table gains electrons most readily and why?
Group-17 in the periodic table gains electron most readily. The elements in this group require only one electron to complete its octet.
What are the general properties of the elements in the group on the right side of the periodic table?
The elements present at right side groups of the periodic table are non-metals. They have high electron affinity and ionization energy.
What elements properties can be predicted from?
An elements property can be best predicted from the group it is in the Periodic Table. Groups (the columns of the tables) of elements have similar properties due to their similar electron configuration of the valence shell.
Where on the periodic tables are the metals located?
Metals are located on left side in periodic table.Eg-group 1,2 elements
