As you go down group 1, the atomic number and Atomic Mass increase. Electronegtivity decreases and atomic radius increases.
What else can I help you with?
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
What is the general trend of the melting points of elements on the periodic table?
The general trend of melting points of elements on the periodic table increases from left to right across a period and decreases down a group.
What is the difference3 between a family of elements and elements in the same period?
a family is a column of elements a period is a row of elements
How does valency of elements vary going down a group?
The valency of elements tends to remain constant or increase by one going down a group on the periodic table. This is because elements in the same group have the same number of valence electrons, which determines their valency. As you move down a group, the number of electron shells increases, allowing elements to either maintain their valency or increase it by gaining electrons to achieve a full outer shell.
What happens to the size of the atoms as you move down the periodic table in group 7?
Down the group, size increases. Because number of shells increases.
What happens to elements as you move down the periodic table?
they do something
What is a row of elements acros the periodic table called?
A PERIOD. NB A columns down the table is a GROUP.
What happens to the radii of the elements between 2 highest peaks?
The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.
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
What is the term for a row of elements going from up to down on the periodic table?
Group or family
What is the name given to the arrangement of elements going up and down on the periodic table?
A group.
Where is the halogen gases found on the periodic table?
The Halogens are from Florine and down. They are the group 17 elements.
In the perdiodic table a group runs down the table true or false?
True. Its a matter of the number of electrons in the outer shell. Elements in the same group have the same number.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
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 is the general trend of the melting points of elements on the periodic table?
The general trend of melting points of elements on the periodic table increases from left to right across a period and decreases down a group.
How are the elements in the periods in the periodic table related?
As you go down a group, the number of electrons in the outer shell is the same.
