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.
When the three elements se te and br ara arranged in order of increasing atomic radius?
The atomic radii of elements follow a general trend: As you move down a group on the periodic table, atomic radius generally increases. Among the three elements mentioned, Se would have the largest atomic radius, followed by Te, with Br having the smallest atomic radius.
How does the atomic radius change from left to right in Groups 1 and 2?
The atomic radius increases from top to bottom in groups 1 and 2 of the modern periodic table. This happens because the number of energy shells increase and are occupied by the increasing number of electrons. As the subsequent shells are completed they are located further from the nucleus due to the decreasing force of attraction between nucleus and the electrons. This leads to an increase in atomic radius. == == Atomic radius is a result of the completion of orbitals as atoms get heavier by adding neutrons and protons to the nucleus. The larger nucleus can hold more electrons. The cloud of electrons determines the atomic radius. Each completed orbital (S,P,D or F) takes up room. The higher orbitals have a greater radius . Unlike the old Bohr theory of atoms (little electrons in orbits around the nucleus), the new probability distribution interpretation of the electrons leads to spherical or hourglass shaped volumes.
Does atomic radius increase left to right in the periodic table of elements?
Generally it decreases. There are a few exceptions: the noble gases tend to be quite a bit bigger than the corresponding halogens, and there's a smaller bump as you go from d-block elements to p-block elements.
What trend is seen in atomic size going down the periodic table?
What trend is seen in atomic size going down the Periodic Table?
Can you describe the general trend in atomic radius in group 2A?
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
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.
How does calcium's atomic radius compared to magnesium radius and potassium radius?
The atomic radius of calcium is larger than magnesium but smaller than potassium. This trend is consistent with the periodic trend across Group 2 elements where atomic radius increases down the group due to additional electron shells. Additionally, going across a period from left to right, atomic radius decreases due to increasing nuclear charge pulling electrons closer.
What trend in atomic radius occurs down a group in the periodic table?
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.
Which atom has larger atomic radius Rb or Xe?
Xe has a larger atomic radius than Rb because atomic radius generally increases from top to bottom within a group in the periodic table. Xe is located below Rb in the periodic table, so it has more electron shells, resulting in a larger atomic radius.
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 BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
What trend does the atomic radius along a period on the periodic table?
The atomic radius decreases along a period. It is because of increasing effective nuclear charge along a period.
What trend does the atomic radius follow along period on the periodic table?
The atomic radius gets smaller the farther right it appears on the Periodic Table, until the addition of a new orbital increases the size again.
What trend does the atomic radius following along period on the periodic table?
The atomic radius gets smaller the farther right it appears on the Periodic Table, until the addition of a new orbital increases the size again.
