Not sure what you mean by "numerical portion," since the gram-atomic weight is a number. Basically, gram-atomic weight (or gram-molecular weight when molecules, like CO2 or H20, are involved) is the amount of a substance in grams equal to its atomic weight. The atomic weight of an element is equal to the sum of its protons and neutrons in its nucleus. The number is often expressed as an integer: 16 for Oxygen, for example. More precisely, it is 15.9994, because of the existence of isotopes of Oxygen that have fewer neutrons in their nuclei than the most common isotope. The 15.9994 value represents the weighted average of all the atomic weights of all isotopes of Oxygen.
The atomic weight in grams per mole of an element is the average mass of one mole of atoms of that element, measured in grams.
No, the atomic weight of an element is not equal to the number of protons minus the number of neutrons. Atomic weight is the average weight of an element's isotopes taking into account their abundance, which includes the sum of the protons and neutrons in the nucleus.
The element with an atomic weight of approximately 912.2 is uranium (U), specifically the isotope uranium-238. Uranium is a naturally occurring radioactive element with a variety of applications, including nuclear power generation and weapons development.
The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass of the element.
Iron (Fe) has an atomic weight of 55.845.
The Atomic Mass of an element is the numerical average of all the masses of the naturally occurring isotopes of that element proportionately. Man made elements do not count in supposedly. IE: If we have an element with atomic weight 100 and we have an isotope of that element with atomic weight 102 and if they occurred equally in nature then the Atomic Mass would be 101.
By weight or volume.
No, isotopes of the same element are of different weight.
The element of Antimony (Sb) would have the atomic weight of 121.75.
Water
Sulfur (32.065)
The protons and neutrons are the main contributors to the weight of an atomic element.
Losing weight requires patience, exercise and the proper nutrition. Diet nutrition weight loss begins by evaluating how much food is eaten and monitoring portion sizes. Portion sizes can make a big difference when attempting to lose weight, or maintain weight loss. Many unintentionally eat too much at meals because they misunderstand the size of the portion. Portion control plates or a measuring scale can help with preparing meals and watching how much is eaten. This is often recommended to help get a feel for how large or small a portion is for snacks and meals.
Mass is a measure of the amount of matter in an object and is constant, regardless of the gravitational force acting on it. Weight, on the other hand, is the force exerted on an object due to gravity and can vary depending on the strength of the gravitational field. The numerical difference between mass and weight is that weight is a force and is measured in newtons (N), while mass is measured in kilograms (kg) or grams (g).
That element is Oxygen by 46.6%
This is a chemical element with a specific atomic weight.
