What is the atomic number and atomic mass of platinum?
The atomic number of platinum is 78, which means it has 78 protons in its nucleus. The atomic mass of platinum is approximately 195.08 g/mol, which is an average of the different isotopes of platinum found in nature.
How much smaller is atomic mass than a kilogram?
ex: 14 ounces is smaller than a pound
ex: 18 ounces is greater than a pound
Why the atomic mass of chlorine is 35.5 you?
This is because the chlorine have two type of isotope one atomic mass have 35 and other is having 37 it is found in the ratio of 3:1 so
= 3 x 35 + 37/4
= 35.5u
What is the atomic mass of the element boron?
The atomic number of Boron (B) is 5.
The atomic weight of B is 10.811 grams per mole. See the Web Links and the Related Questions to the left of this answer for a periodic table and more information about this element.
What does the atomic mass of an element repreasent?
The atomic mass of an element represents the average mass of an atom of that element, taking into account the abundance of its isotopes. It is measured in atomic mass units (amu) and is valuable in determining the element's properties and behavior in chemical reactions.
What is the mass number of neon (Ne)?
Neon has two stable isotopes, namely the mass numbers 20 and 22. According to relative abundance, it has 20.2 RAM.
If the atomic mass of an element is x what is the mass in grams of 6.021023 atoms of the element?
To find the mass of 6.02 x 10^23 atoms of an element, you would multiply the atomic mass of the element (x) by Avogadro's number (6.02 x 10^23 molecules/mol) to get the mass in grams. The result would be x grams.
How can you use the nuclide symbol to determine how many neutrons a particular isotope has?
The number of neutrons is the difference between the mass number and atomic number. For example U-235 means mass number equals 235. If we know that thge uranium atomic number is 92, then the number of neutrons for U-235 is 235-92 = 143 neutrons.
What is the atomic mass and neutrons are K?
The mass number of Potassium is 39 which means it has 20 neutrons.
In mass communication mass denote as?
In mass communication, "mass" refers to a large and diverse audience that the message is intended to reach. This audience can include a broad segment of the population with various backgrounds, interests, and characteristics. The goal is to reach as many people as possible simultaneously through channels like television, radio, or social media.
What has a mass of 1.67495x10?
You left out part of this statement. One neutron has a mass of 1.67495x10^-24g.
What is the gram atomic mass for the element Nb?
The gram atomic mass of niobium (Nb) is approximately 92.91 grams per mole.
What does the atomic mass and number tell you about an atom?
The atomic weight (not mass) of a chemical element is the ratio between the average mass of the atoms of this element to 1/12 from the Atomic Mass of carbon-12.
The atomic mass is a term applied only to specific isotopes; the unit is the same as above. Is a value denoting the total mass of all the protons, neutrons, and electrons in an isotope.
The mass number tells us the number (the sum) of protons and neutrons in the nucleus of an atom.
The atomic number, on the other hand, tells us how many protons are in the nucleus of an atom.
IUPAC publish periodically tables of atomic weights - the last edition is from 2009-2010.
For the atomic masses of isotopes the last published edition is The AME 2003 atomic mass evaluation, edited by Audi, Wapstra and Thibault.
The mass of a die depends on what it is made of and how big it is. The mass of dice also depends on how many there are.
This is a consequence of the law of periodicity of chemical elements.
