Why does rubidium have a larger radius than silver?
Rubidium has a larger atomic radius than silver primarily due to its position in the periodic table. Rubidium is an alkali metal located in Group 1, while silver is a transition metal in Group 11. Rubidium has fewer protons and electrons, resulting in a weaker effective nuclear charge on its outermost electron, allowing it to be more loosely held and thus increasing its atomic radius. Additionally, rubidium has more electron shells compared to silver, contributing further to its larger size.
What happens to the radii of rubidium and strontium?
The radius of strontium is smaller than the radius of rubidium.
How long is Rubidium's half life?
Most rubidium (about 72.2%) is of the isotope 85Rb, which is stable. The remainder of natural rubidium (about 27.8%) is of isotope 87Rb, which has a half life of 4.88 x 1010 years and decays into 87Sr. There are a number of other isotopes of Rubidium, all of which are synthetic, having half lives ranging from less than a microsecond to something more than 86 days.
Does rubidium and strontium ion have the same electronic configuration?
NO!!!! Each element has it own ground state electron configuration. Rubidium is [Kr] 5s1 Strontium is [Kr] 5s2. Notice that strontium has one MORE electron than Rubidium. The symbol [Kr] is shorthand for the full electron configuration of krypton.
What is rubidium ionization energy?
the 1st ionization energy is 403.03 kJ/mol.. since it's oxidation state is +1, you don't normally take away more than one electron so the 2nd and 3rd ionization energies are much larger and don't usually matter
What is more active iron or silver?
Iron is several times more active than silver.
Why is rubidium more active than sodium?
I'm not 100% sure but it may be because it unsaturated

Which is more active silver or copper?
Copper is more active than silver. Copper reacts more readily with other substances compared to silver, which is less chemically reactive.
What is more reactive rubidium or krypton?
Rubidium is more reactive than krypton. Rubidium is an alkali metal and reacts vigorously with water, while krypton is a noble gas and is inert under normal conditions.
Why is rubidium more reactive than sodium?
Rubidium is more reactive than sodium because rubidium has a larger atomic radius and fewer electron shells, making it easier for rubidium to lose an electron and form a positive ion. This tendency to lose an electron increases its reactivity compared to sodium.
Is rubidium harder or softer than potassium why?
Rubidium is softer than potassium. This is because rubidium has larger atomic size and higher reactivity, which makes it more easily deformable when compared to potassium.
What has two more protons and two more electrons than bromine?
Rubidium
Which atom has 2 more protons and electrons than bromine?
Rubidium.
Does rubidium float or sink?
Rubidium is a metal, so it is denser than water and will sink when placed in it.
Why does rubidium have a larger atomic radius than sodium?
Rubidium has a larger atomic radius than sodium because rubidium has more electrons and energy levels, leading to increased electron-electron repulsion and a larger atomic size. Additionally, the outermost electron in rubidium is in a higher energy level compared to sodium, contributing to a larger atomic radius.
Is a rubidium larger or smaller than a neutral atom?
A rubidium atom is larger than a neutral atom because, when it loses an electron to become an ion, it loses an electron from the outermost shell, increasing the effective nuclear charge which attracts the remaining electrons closer to the nucleus, reducing the size of the ion compared to the atom.
