Given any two elements within a group is the element with the larger atomic number likely to have a larger or smaller atomic radius than the other element?

The atomic radius decreases across a period from left to right and
increases down in a given group. That means that since the lower the element is in a group, the larger the atomic radius will be. The atoms with the largest atomic radii are located in Group I and are at the bottom of groups.

As you move from left to right across a row on the periodic table the radius actually decreases due to a stronger pull from the nucleus. As you move down a column on the Periodic Table, however, the radius gets larger. so while potassium has a larger radius then bromine, rubidium has a larger radius then potassium.

Meaning of substage?
A smaller stage within a larger one
Are chromosomes larger than a cell?
No, chromosomes are smaller than cells. Chromosomes are found in the nucleus of cells which codes for the synthesis of proteins.
Does cooling rate affect solubility?
slower rates of cooling will create larger crystals, rapid cooling allows little time for element accumulation in the crystal, therefore, the crystals created will be smaller. larger, visible crystals in igneous rock indicate that the magma was slow cooling, usually at depth. much smaller crystals in igneous rock indicate rapid cooling of lava, usually at or near the surface. crystals in igneous rock will grow larger and have more to accumulate material for their growth the more they have at their crystallization temperature.
What is one benefit to an organism of being large?
It takes less cells to do the job. If you cut yourself, then your body can send less cells to heal the wound compared to when the cells are smaller. You need more cells when you are smaller then when you have the larger cells.
Is a cell larger than a bread crumb?
That depends on the size of the breadcrumbs but no, most cells are smaller than a breadcrumb.
Which element in each pair has atoms with a larger atomic radius selenium oxygen?
For the representative elements (main group elements), atomic radius generally decreases from left to right across a period. Example: B and Fl: Fl has the smaller atomic radius Li and Be: Be has the smaller atomic radius
Element M reacts with chlorine to for a compound MCl2 Element M is more reactive than magnesium and has a smaller radius than barium the element is?
Element M can be a choice of 4 elements, Beryllium, Magnesium, Calcium, or Strontium. The element must have an oxidation of +2, which means group 2 elements. The atomic radius of a barium atom is 222pm. Radium has a larger atomic radius that Barium, so that is eliminated, and Barium is the same as Barium so that is also eliminated.
Which element will have a larger atomic radius magnesium or cesium?
Caesium atom has a larger atomic radius.
What element has larger atomic radius than rubidium?
nitrogen- .70 angstroms (oxygen- .66 angstroms)
Is boron atomicly bigger or smaller than Oxygen?
Boron has a larger atomic radius but a smaller atomic mass.
Which has smaller atomic size helium or fluorine or neon?
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
How do you use the word atom in a sentence?
The atom is the smallest particle of an element that has its unique chemical properties. Smaller atoms are formed from a larger one in the process of atomic fission. Heavy elements can be synthesized by bombarding an atom with other atoms, or with neutrons.
What element has a larger atomic radius Magnesium or Bromide?
Bromide.
Which element has a larger atomic radius carbon or germanium?
geranium
What are the three exceptions in the periodic table?
This question is a little bit cryptic. I think I can decipher what it means though. When Mendeleev introduced his periodic law, he expressed it in something like these terms:If the elements are arranged in order of increasing atomic weight, there is a periodic recurrence of elements with similar properties.Now in Mendeleev's time -- around 1870 -- not all of the natural elements were known, and even for those that were, not all atomic weights were known accurately enough.When Mendeleev produced his second periodic table in 1871-- a table of elements arranged so that the periodic recurrence of similar elements could easily be seen, he had to make some "adjustments" to the atomic weight values that were generally accepted at the time. In most cases he was right to say that the accepted atomic weights were wrong, but in one case he was quite wrong about an atomic weight. The atomic weight of tellurium, a rare element that belongs in the sulfur family proved to be significantly larger than that of iodine, which belongs in the chlorine family. It simply did not fit with the periodic lawas Mendeleev understood it.By the year 1900, this anomaly had been joined by two others: nickel and cobalt, and argon and potassium.In 1913 an English chemist/physicist, Moseley, discovered the atomic number, and the modern version of the periodic law says thatIf the elements are arranged in order of increasing atomic number, there is a periodic recurrence of elements with similar properties.Usually, an element with larger atomic number has a larger atomic weight, but there are just these three examples where this is not the case.• Element 18, argon, has atomic weight 39.95, but element 19, potassium has atomic weight 39.10• Element 27, cobalt, has atomic weight 58.93, but element 28, nickel, has atomic weight 58.71• Element 52, tellurium, has atomic weight 127.60, but element 53, iodine, has atomic weight 126.90I think that these are probably the "three exceptions" that your question is referring to.
Which element has a larger atomic radius silicon or lead?
Atomic radius of Si is 111pm.Atomic radius of Pb is 175pm.Therefore lead has a larger atomic radius than silicon.
When masses combine to form elements with larger masses?
Atomic fusion occurs when masses combine to form elements with larger mass.
