an atom is larger than an element
anion is always larger than its parent atom
An atom that has gained one or more electrons, becoming a negative ion, is larger than its parent atom.
Scandium is slightly larger than Titanium due to one unit less nuclear charge.
No. It is smaller.
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.
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.
pretty much everything is larger than an atom.
its larger
an atom is larger than an element
Larger.
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.
It becomes an ion with a larger radius than the atom of chlorine
No. A cesium atom is larger both in terms of atomic mass and atomic radius.
anion is always larger than its parent atom
an atom is larger than an electron
An atom that has gained one or more electrons, becoming a negative ion, is larger than its parent atom.
