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
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 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 is the trend in electronegativity of elements when going down the group?
Electronegativity increases as you go along a group/family Everything about elements increases as you go farther down and to the right of the periodic table except the radius, in which the largest elements are at the bottom left, and the smallest at the top right
Which element in group 6 is the most reactive?
Elements are more reactive as you go down the periodic table and to the left.
What happens to elements as you move down the periodic table?
they do something
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 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
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.
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.
Where is the halogen gases found on the periodic table?
The Halogens are from Florine and down. They are the group 17 elements.
What is the cause of periodicity amongst elements in periodic table?
as the no of valence electrons are same down the group
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 size of the atoms as you move down the periodic table in group 7?
Down the group, size increases. Because number of shells increases.
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.
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
