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.
What else can I help you with?
What happens to the size of the atoms as you go down this group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
What is the trend in atomic size in the series of Group IIA elements Be through Ra?
The atomic size increases as you move down the Group IIA elements from Be to Ra. This trend is due to the increase in the number of electron shells as you move down the group, leading to greater atomic radius.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Does a nonmetallic character increase or decrease down a group?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
What causes the atomic size to increase within the groups of the periodic table?
The atomic size increases within a group in the periodic table due to the addition of energy levels as you move down the group. As you go down a group, each element has one more energy level than the one above it, leading to an increase in atomic size.
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
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.
What happens to the size of the atoms as you go down this group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
What is the trend in atomic size in the series of Group IIA elements Be through Ra?
The atomic size increases as you move down the Group IIA elements from Be to Ra. This trend is due to the increase in the number of electron shells as you move down the group, leading to greater atomic radius.
What happens to the group 1 elements as you go down the table?
As you go down Group 1 in the periodic table, the reactivity of the elements increases due to the decrease in ionization energy and increase in atomic size. The metals become more reactive with water and air as you move down the group.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Does the size of atoms increase remain the same or decrease from the top to the bottom of a group of elements?
yes
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.
Does a nonmetallic character increase or decrease down a group?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
Does elements on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
Atomic size generally decreases as you move across a period from left to right due to increasing effective nuclear charge. However, atomic size tends to increase as you move down a group due to the addition of more electron shells.
What is the group trend in p-block element?
The p-block elements show a trend in increasing atomic size and decreasing electronegativity as you move down a group. They also exhibit an increase in metallic character and reactivity towards metals, along with a decrease in ionization energy moving down the group.
Why group 7 elements get more reactive as you go down the group from fluorine to iodine?
Group 17 elements (group 7) become more reactive as you move down the group due to the increase in atomic size and shielding effects. As you go down the group from fluorine to iodine, the outermost electron shell gets farther from the nucleus, leading to weaker attraction, making it easier for the elements to gain an electron and become more reactive.
