What tells us about the similarities in the chemical properties of the elements in a group on the periodic table?
well, basically the elements in the modern periodic table are arranged in the increasing order of atomic number. the elements are arranged in a group according to the valance electron. all elements in a group have same valance number of electron making the elements in group possess similar properties. further more as we go down the periodic table metalic character increases...
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
How does the reactivity of the elements in group 2 change on descending the group?
As you go down the Group 2 (alkaline earth elements) elements they become more and more reactive. i.e. H2O+Ca=Ca(OH)2+H2 there is more hydrogen (g) created and at a faster pace than H2O+Mg=Mg(OH)2+H2.
Why do elements get larger moving down a group?
Elements become larger in atomic radius because they have an increased number of electrons, which increases the level of shielding, which causes the nuclear influence to become less strong on the outer level of electrons allowing them to space farther apart.
Why does the size of the elements increase down a group?
The atomic numbers of the elements down a group increase. this means, more electrons. More electrons mean more shells. More shells mean larger radius. Larger radius is nothing but larger size. Thus, the number of electrons or shells is the reason why the size of the atom of elements increase down the group.
Are elements in the front rows more metallic than the elements in the last row?
Metalic Nature DECREASES as you move across a period (horizontal rows) from left to right. It INCREASES as you go down a group (the vetical collums)
What kind of group one are the most reactive?
The elements in group 1 become more reactive as you go down the group.
As you go down a group the elements generally become more or less metallic?
more~
How many elements on the periodic table of elements?
In the Periodic table of Elements There are 118 Elements 96 are metals The rest are non-metals Group 7= Halogens Group 8/0= Noble gases Going down group 1 and 2, elements become more reactive

Why group 7 elements get more reactive as you go down the group from fluorine to iodine?
There can not be any reason, because the premise is not true: Group 7 elements become less rather than more reactive from fluorine to iodine.
What are the most reactive elements in the group of akali metals?
Alkali metals are the elements in the 1st group. In the 1st group,the reactivity of the elements increase down the group. Cs is the most reactive alkali metal.
How does valency of elements vary going down a group?
me
What is the similarity and the difference between the two elements found in the same group?
As we move down the group ,the electrons in the valence shell remains constant but the number of shells increases by one.size of the element increases down the group .elements are more electro-positive as we move down the group so elements at the bottom are more electro-positive than those at the top.as the size of the elements increases the nuclear charge on the elements decreases.due to less nuclear charge shielding effect decreases down the group.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What do elements in each group or family have in common?
elements in a group have the same number of valence electrons. The number of shells present increases as we move down a group.
How does the reactivity of the elements in group 2 change on descending the group?
As you go down the Group 2 (alkaline earth elements) elements they become more and more reactive. i.e. H2O+Ca=Ca(OH)2+H2 there is more hydrogen (g) created and at a faster pace than H2O+Mg=Mg(OH)2+H2.
