Atomic Mass

Neutrons have a slightly higher atomic mass compared to protons. Neutrons weigh approximately 1.0087 atomic mass units, while protons weigh approximately 1.0073 atomic mass units.

Iodine is a metal element. Atomic mass of it is 127.

The atomic mass of Ca-43 is approximately 43 amu (atomic mass units). This value represents the total mass of an atom of calcium-43, taking into account the protons, neutrons, and electrons that make up the atom.

Manganese is a metal element. Mass number of it is 55.

The chemical element halogen bromine (Br) has an atomic weight (not mass) of 79,904 and 35 protons.

(mass of A) x (%of A) + (mass of B) x (% of B) + (mass of C) x (% of C)

Fluorine is a non metal element. Atomic mass of it is 19.

Straight up, atomic number identifies the element. And it is determined solely by the number of protons in the nucleus of that atom. The electron count will match the proton count in a neutral atom. Neutron count, and, therefore, atomic mass, can vary because there are different isotopes of a given element around. Just as one example, most hydrogen has a single proton for a nucleus, but some hydrogen has a neutron attached to that proton. In even rarer cases, hydrogen can have two neutrons hanging onto that proton. Here's one element, with one set of chemical characteristics, and three different atomic masses. Best to go with atomic number than atomic mass when considering chemical properties.

No, the atomic radius and atomic mass are not the same. The atomic radius refers to the size of an atom, typically measured as the distance from the nucleus to the outer electron cloud. On the other hand, atomic mass is the mass of an atom, which is the sum of the protons and neutrons in the nucleus.

Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.

The element with the atomic mass of 118.69 is tin, symbol Sn.

Context switch must be atomic to ensure that the state of the system remains consistent during the switch. This is important because a context switch involves saving the state of the current process and loading the state of the next process. If the switch is not atomic, it could lead to data corruption or inconsistencies in the system, resulting in unpredictable behavior.

When an electron moves from a lower to a higher energy level, it absorbs energy and jumps to a higher orbit. This process is known as excitation. The electron can then release this absorbed energy as light when it moves back down to a lower energy level.

To calculate the average atomic mass of chlorine, you would take the abundance-weighted average of the isotopes of chlorine. This involves multiplying the atomic mass of each isotope by its relative abundance (in decimal form), then summing all the products.

atomic mass number - protons = number or neutrons

Sulphuric Acid does NOT have an Atomic Mass. It has a Molecular Mass, because it is a molecule, not an atom.

Refer to the Periodic Table.

The formula for sulphuric acid is H2SO4

This tells us that there are two atoms of hydrogen , one atom of sulphur and four atoms of oxygen.

So from the Periodic Table we read off the atomic masses for each element.

Hence

2 x H = 2 X 1 = 2

1 x S = 1 xs 32 = 32

4 x O = 4 x 16 = 64

2 + 32 + 64 = 98 the Molecular mass of sulphuric acid.

Most elements have more than one isotope stable against radioactive decay, and these isotopes, each of which individually has an integral mass number, occur naturally in amounts that do not lead to integral average gram atomic masses.

A non-enhancing mass typically refers to a lesion or abnormal tissue growth that does not show increased contrast uptake on imaging studies like MRI or CT scans. This can indicate a benign or stable condition, but further evaluation and monitoring may be needed to confirm the nature of the mass.

The mass number is the sum of protons and neutrons in the atomic nucleus of chemical elements. All mass numbers are integers.

The atomic weight is not an an integer because is calculated taking in the account the isotopic composition of an element; also the mass excess has a role.

The atomic number of iodine (I) is 53.

The atomic weight of I is 126.90 grams per mole.

Iodine is a diatomic molecule, I2.

A polypoidal mass refers to a growth that appears as a polyp or protrusion from a surface, typically seen in certain medical conditions like polyps in the colon or nasal polyps. These masses can vary in size and shape and may require medical evaluation and treatment to determine if they are benign or potentially cancerous.

The relative atomic mass of an atom can be determined by averaging the masses of its isotopes based on their abundance in nature. This value is reported relative to the mass of a carbon-12 atom, which has been assigned a relative atomic mass of exactly 12.ø

Gallium is a metal element. Atomic mass of it is 70.

The main reason the mass of an atom is expressed in atomic mass units rather than in grams is that the mass of an individual atom is extremely small, typically in the range of 10^-23 grams. Using grams would result in cumbersome decimal numbers, while atomic mass units simplify calculations and comparisons of atomic mass.
