We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
Nitrous Oxide is not an element, therefore it doesn't have atomic mass. An element is a substance in the form of solid, liquid, gas or metalloid, which can not be broken down anymore. For example, Tin is not an element because it is made up of different elements. Oxygen is just oxygen it is not made out of anything but oxygen atoms. :) BTW I'm a 8th grader that learned this is Science class and made a 102 on the test of the periodic table, elements and the atoms that make them up.
Yes Look at the last number. if its even, it is divisible by 2 BTW, it equals 29231
Sorry btw the question is there are 30 pupils in a class 26 have mp3s and 22 have mobiles. What is the smallest number of pupils who can have both
The percent sign (%) represents the symbol for percentage or "out of 100." It is used to indicate a proportion or a relationship between a part and the whole. In mathematical terms, it is often used to express a fraction or decimal as a percentage.
It means to take the number like 24 and round it to the closest ten which is 20 not 30. BTW watch your english Hope This Helps! :)
Neutron is the difference btw the atomic no and the mass no of an element.
look on a periodic table. (it's 8 btw)
First some basic terminology for the periodic table:Atomic number: The number of protons in the element's nucleus.Atomic mass: The total mass of the protons, neutrons, and electrons that make up a particular isotope of an elementAtomic weight: The average weight of an elemental atom, taking into account the relative abundance of the element's isotopes. This is getting to the crux of your question - I may not have explained atomic weight that well, but the example of Cl below will better illustrate what I mean by atomic weight. (And btw, 'mass number' isn't a correct way to refer to the atomic weight.)Take the example of Chlorine, or Cl. There are two main isotopes of Cl, 35Cl and 37Cl (there are others but they are very rare, so we'll simplify). We'll now calculate the atomic weight (or as you referred to it incorrectly, mass number) based on the relative abundance and atomic masses of these two isotopes. I'm going to round to even numbers to symplify.Chlorine has an atomic number of 17, so we know all of its isotopes have 17 protons (and therefore 17 electrons).35Cl has 17 protons, 17 electrons and 18 neutrons, while 37Cl has 17 protons, 17 electrons, and 20 neutrons.Because 35Cl and 37Cl have the same number of protons and electrons (as do all isotopes of the same element) they behave very similarly. They are isotopes since they have different numbers of neutrons, and therefore 35Cl and 37Cl have different atomic masses.35Cl has an atomic mass of 35, and 37Cl has an atomic mass of 37.Since 35Cl makes us almost 77% of all Cl isotopes on earth, and 37Cl makes up almost all of the remaining 23% of Cl isotopes on earth, we get the atomic weight by calculating the average weight of Cl.Atomic weight = (% abundance of isotope A * atomic mass of isotope A) + (% abundance of isotope B * atomic mass of isotope B)Atomic weight of Chlorine = (0.77 * 35) + (0.23 *37)Atomic weight of Chlorine = 35.46

Taoism is all about man's relationship with nature, while Confucianism is all about man's relationship with his fellow man.

there are 121 neutrons in Mercury This is CORRECT. The number of protons (80) is equal to the number of electrons and it is also the atomic number. You can figure out the number of neutrons by subtracting the atomic weight by the atomic number. For example: Mercury Atomic number: 80 Atomic weight: 201 --> 201 - 80 = 121 which is the number of neutrons BTW this works with all the elements on the periodic table
YES!!! Answerer 2: Abseloutly BTW I LOVE YOU
In a neutral atom the number of electrons is equal to the number of protons. The opposite charge between protons and electrons is what allows for a neutral atom.
It reached number 35. Metallica rules btw \m/
