Arranging Se, Te, and Br in order of increasing atomic size, you get:
Br --> Se --> Te
The trends are: atomic size increases right to left, and top to bottom.

What trend in atomic radius do you see as you go down a group on the periodic?
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
What element has larger atomic radius than rubidium?
nitrogen- .70 angstroms (oxygen- .66 angstroms)
When atoms gains electrons what happens to the atomic radius?
The negative ionic radius is larger than the neutral atomic radius
What is larger than the atomic radius of P?
There are many elements with atomic radii larger than that of P. Several examples would be Si, Al, Mg, and Na.
What element has the smallest radius?
It is helium that has the smallest atomic radius. Use the link below to see a list of elements arranged by atomic radius.
The elements on the periodic table are arranged in order of increasing?
1) Elements on the modern Periodic Table are arranged in order of increasing: (a) Atomic mass 5 As the elements of Group 17 are considered in order of increasing atomic number, there is an increase in: (1) Atomic radius 7) In the wave-mechanical model of the atom, orbitals are regions of the most probable locations of: (4) electrons 2 Which phrase describes an atom? (3) A negatively charged electron cloud surrounding a positively charged nucleus 3 Which total mass is the smallest? (1) The mass of 2 electrons
What are the elements from group 2 on the periodic table arranged in order of increasing atomic radius?
The periodic table is arranged in order (across and down the rows) in increasing number of protons in the nucleus; as the number of proton increases the radius of the nucleus generally increases - thus the order is the order reading down group 2: beryllium (least), magnesium, calcium, strontium, barium and radium (largest).
How do you arrange the following elements in order of increasing atomic radius from 1 (smallest radius) to 4 (largest radius). Sb As N and P?
N, P, As and Sb
How do you arrange the following elements Sb As N and P in order of increasing atomic radius from 1 (smallest radius) to 4 (largest radius).?
N, P, As and Sb
What element has the smallest atomic radius?
Helium usually is listed with the smallest atomic radius when calculated. Hydrogen however has a smaller van der Waals radius The protium isotope of hydrogen has the smallest nucleus radius. It is 1.6 fm
How do you tell the size of an elements atomic radius?
The atomic radius of chemical elements is expressed in picometers (pm).
What trend in atomic radius do you see as you go down a group on the periodic?
The atomic radius of elements increases as you go down a group. This increase in radius as you go down a period is primarily caused by the increasing principal quantum number of the outer electron shells.
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
Is the atomic radius the same as the atomic mass?
no atomic radius is not the same as atomic mass because it is 10 to the power of 10 and atomic mass is different for different elements
Elements like francium located at the bottom of a group have a lower attraction for their valence electrons because they have a?
large atomic radius.large atomic radius.
How are period and group trends in atomic radii are related to electron configuration?
The atomic radius decreases along the elements across a period. Along a group, there is an increment in the atomic radius of corresponding elements.
