# How Would You Define Atomic Mass In Plain English

## How would you define atomic mass in plain English?

The amount of matter that makes up an element’s atom, or atomic mass. It is written as a multiple of 1 point992646547 1023 gram, which is equal to one-twelfth of the mass of the carbon-12 atom, which has an atomic mass of 12 units. The term atomic mass refers to an element’s individual atom’s mass. A substance’s molecular mass is the total of all the atomic masses of the atoms that make up that molecule or compound.An atom is the smallest unit of an element and is defined as having a nucleus that contains neutrons, protons, and electrons as well as sharing the chemical properties of the element.Explanation: An atom is the smallest unit of an element. In an atom, subatomic particles like protons and neutrons are present inside the nucleus and negatively charged electrons are present in the extranuclear part.An atom is a part of matter which is small in size and exhibits the properties of the element. Some atoms exist non-independently by forming ions and molecules. Molecules are formed when one or multiple atoms combine by chemical bonds. It is the smallest constituent of an element that exhibits its properties.

## What is the atomic mass class 11?

What is Atomic Mass? Atomic mass of an element is the number of times an atom of that element is heavier than an atom of carbon taken as 12. One atomic mass unit is equal to one-twelfth of the mass of an atom of carbon 12 isotope. Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element’s nucleus. It is the average weight of an element. It is the total number of protons in the atom’s nucleus.Atomic mass is roughly equal to the sum of the individual particle masses of an atom. Atoms have three basic components: protons (positively charged particles), neutrons (non-charged particles), and electrons (negatively charged particles).Relative atomic mass is the average mass of one atom of an element on a scale where an atom of carbon-12 has a mass of 12. The formula mass or molecular mass of a compound is simply the sum of the atomic masses of its constituent atoms. For example, a molecule of water contains two hydrogen atoms and one oxygen atom.Atoms have a mass that is based largely on the number of protons and neutrons in their nucleus. The atomic mass of each element in the Periodic Table is the weighted average of the mass of all its isotopes.A unit of mass used to express atomic and molecular weights, equal to one-twelfth of the mass of one atom of carbon 12. It is also known as Dalton. Mole:- Standard scientific unit for meaning large quantities of very small entities such as atoms molecular or other specified particles.

## Where is the atomic mass?

Experimental data showed that the vast majority of the mass of an atom is concentrated in its nucleus, which is composed of protons and neutrons. The mass number (represented by the letter A) is defined as the total number of protons and neutrons in an atom. An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of any isotope of any element is expressed in relation to the carbon-12 standard. For example, one atom of helium-4 has a mass of 4. An atom of sulfur-32 has a mass of 31.The molar mass of the compound is defined as the total mass of atoms in grams present in a mole of a molecule. On the other hand, atomic mass is termed as the mass of the atom. In other words, it is the mass of one mole of the compound or Avogadro number of particles, i.An atomic mass unit(symbolized AMU or amu) is defined as precisely 1/12 the mass of an atomof. The carbon -12 (C -12)atom has six protons and six neutrons in its nucleus.What is atomic mass? Atomic mass is the average mass of the protons, neutrons, and electrons in an atom. Its unit is a unified atomic mass and is denoted by the symbol ‘u’.

## What is an atomic mass answer?

The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu. By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu. Therefore, the atomic mass of an individual atom can be said to equal the total number of protons and neutrons. For example, fluorine atoms typically have 9 protons and 10 neutrons, and therefore have an atomic mass of 19 amu.The atomic mass of an element is the number of times a molecule of that element is heavier than an atom of carbon taken as 12. One atomic mass unit is equal to one-twelfth of the mass of a particle of carbon 12 isotope.The atomic number is the number of protons in the nucleus of an atom. The number of protons define the identity of an element (i.
