the answer is A
Chromium is a metallic element. Mass number of it is 52.
Tellurium is a metal element. Atomic mass of it is 128.
They show that the periodic table isn't arranged on the basis of increasing atomic mass because iodine has a mass lesser than tellurium. Iodine has a mass of 126.90 and tellurium has a mass of 127.60.
the 127.6 stands for the relative atomic mass, which is the number of protons and neutrons in tellurium. the number down the bottom indicates the atomic number which for tellurium is 52 so that means there are 52 protons and 127.6 subtract 52 = 75.6 so there are 75.6 neutrons :)
The atomic number of tellurium (Te) is 52.The atomic weight of Te 127.60 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!
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.
I want to know what the atomic mass of tellurium is......... It has not answered my question and I would like to know the answer....
Tellurium-123 has 52 protons and 71 neutrons.
The element with a mass number of 52 could be tellurium (Te) or antimony (Sb). Both of these elements have isotopes with a mass number of 52.
Iodine has a higher atomic number (53) because it has one more proton in its nucleus than tellurium (52). However, iodine's lower atomic mass compared to tellurium is due to differences in their isotopic composition. Isotopes of iodine with lower mass numbers are more abundant, leading to a lower average atomic mass for iodine compared to tellurium.
There are 52 protons in an atom of tellurium. The number of neutrons varies, however, as there are a number of isotopes of this metalloid. There are 70, 72, 73 and 74 neutrons in stable isotopes of tellurium, and 68, 71, 76 and 78 neutrons in four radioactive isotopes which can be found naturally. In all, there are isotopes of tellurium with 53 thorough 90 neutrons. A link can be found below for more information.
The atomic number of tellurium is 52. So there are 52 protons and 52 electrons. the number of isotope depends on the isotope. Te-128 has 76 neutrons. Note: Mass number = number of protons + number of neutrons
