What else can I help you with?
Which element has the smallest atomic radius phosphorus or tellurium?
Phosphorus (1.23 Å) has an atomic radius smaller than that of tellurium (1.42 Å).
Why is melting point of astatine higher than chlorine?
The higher melting point of astatine compared to chlorine is due to astatine being a heavier and larger atom with stronger metallic bonding forces. These stronger forces result in astatine requiring more energy to overcome intermolecular forces and change from a solid to a liquid form at a higher temperature compared to chlorine.
Which is larger a hydrogen atom or francium atom?
A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.
An atom of scandium is larger or smaller than an atom of titanium?
Scandium is slightly larger than Titanium due to one unit less nuclear charge.
What one is larger a chlorine atom or a chloride ion?
A chloride ion is larger than a chlorine atom because it has gained an electron, leading to increased electron-electron repulsion and a larger ionic radius compared to the atomic radius of a chlorine atom.
Which is more stable an atom of tin an ion of tin or an atom of tellurium?
Tellurium is more stable than tin due to the fact that tellurium is closer to having a stable number of electrons on its outer shell than tellurium.
Which element has the smallest atomic radius phosphorus or tellurium?
Phosphorus (1.23 Å) has an atomic radius smaller than that of tellurium (1.42 Å).

What is larger then an atom?
pretty much everything is larger than an atom.
How is it that tellurium has a greater mass number than iodine if an iodine atom has one more proton than a tellurium atom?
Iodine nuclei have one more Proton than Tellurium, but in general the Tellurium atoms have more neutrons, giving a higher average atomic mass. Elements often have isotopes, and their stated atomic masses are averages which look at the abundance of these isotopes. In a given sample of Iodine, 100% of it will be 127I, though the tiniest trace of 129I will exist. In a sample of Tellurium, 65% will be 128Te and 130Te. This makes Tellurium's average atomic mass a little higher than Iodine's.
Is a sodium atom is larger than a silicon atom?
No, a silicon atom is larger than a sodium atom. This is because silicon has more electrons and protons than sodium, leading to a larger atomic radius.
Is molecule larger or smaller than an atom?
Larger.
How many valence electrons would be found in an atom of tellurium?
There are 6 valence electrons in tellurium On the 5th energy level, it's valence shell
Which is larger a hydrogen atom or francium atom?
A francium atom is larger than a hydrogen atom. This is because francium has more electrons and protons in its nucleus, leading to a larger atomic size compared to hydrogen.
Why did mendeleev place tellurium before iodine?
Iodine's atomic number is 53 whereas tellurium's is 52. Atomic number is basically the number of protons that an element has. Therefore, as iodine has more protons than tellurium, it appears later in the table.
Is the model of an atom smaller or larger than the actual atom itself?
The model of an atom is larger than the actual atom itself. Atom models are simplified representations used to help understand the structure and behavior of atoms at a scale that is easier for us to comprehend.
An atom of scandium is larger or smaller than an atom of titanium?
Scandium is slightly larger than Titanium due to one unit less nuclear charge.
