The Atomic Mass will increase. As you go down a group in the Periodic Table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
What else can I help you with?
What trend can be observed among the atomic radii of main-group elements down a group?
The atomic radii of main-group elements generally increase down a group. This is because as you move down a group, the principal quantum number increases, leading to larger atomic orbitals and a greater distance between the nucleus and the outermost electron, resulting in a larger atomic radius.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
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 trend does electroelectricity follow going down the periodic table?
Electronegativity DECREASES going down a group.
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.
What do you predict the trend in atomic mass will be going down a group?
The atomic mass increases down a group.
What trend can be observed among the atomic radii of main-group elements down a group?
The atomic radii of main-group elements generally increase down a group. This is because as you move down a group, the principal quantum number increases, leading to larger atomic orbitals and a greater distance between the nucleus and the outermost electron, resulting in a larger atomic radius.
What is the Group trend Atomic radius?
The group trend for atomic radius is that it tends to increase down a group in the periodic table. This is because as you move down a group, the number of electron shells increases, leading to a larger atomic radius. Additionally, the effective nuclear charge decreases down a group, which also contributes to the increase in atomic radius.
What trend is seen atom size going down the periodic table?
Excepting groups 5-12 of the periodic table.the atomic radius increase down in the group.
What trend is oberserved among the atomic radii of main-group elements down a group. eplain this trend?
The trend of atomic radius increases down a group on the periodic table. This occurs because each successive element down a group has another energy level. As more electrons are added, more energy levels are needed to hold the electrons.
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 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.
What general trend in electronegativity do you note going down a group across a period?
going down a group, electronegativity decreases going across a period, electronegativity increases
What is the trend in atomic radius down a group explain?
The trend in atomic radius increases down a group. This is because as you move down a group, each element has an additional energy level of electrons, leading to a larger atomic radius. The increased number of electron shells results in greater electron-electron repulsion, causing the outermost electrons to be pushed farther away from the nucleus, thus increasing the atomic radius.
What trend does electroelectricity follow going down the periodic table?
Electronegativity DECREASES going down a group.
What is the Atomic polarizability trend?
The atomic polarizability generally increases down a group and decreases across a period. This trend occurs because atoms with larger electron clouds (such as larger atomic size) are more easily polarized. Additionally, atoms with higher electronegativity tend to have lower polarizability due to stronger electron-electron repulsion.
What trend does the first ionization energy follow in the periodic?
It decreases when going down a group.
