Atomic Mass

The atomic mass of AgBr, which is a compound made up of silver (Ag) and bromine (Br) is the sum of the atomic masses of silver and bromine. Silver has an atomic mass of approximately 107.87 g/mol, while bromine has an atomic mass of approximately 79.904 g/mol. Therefore, the atomic mass of AgBr is approximately 107.87 + 79.904 = 187.774 g/mol.

The element with an average atomic mass of 59 amu is cobalt (Co). It is a transition metal with atomic number 27 and is commonly used in alloys and magnets due to its magnetic properties.

That would be oxygen (16O).

the atomic number is 53 and the atomic mass is 126.9 so you would round it up to 127

As you move diagonally across the periodic table, from bottom left to top right, the atomic number increases but the average atomic mass decreases. For example, lithium (Li) to helium (He), sodium (Na) to neon (Ne), or potassium (K) to argon (Ar) would exhibit this trend.

Let x represent the relative abundance of the isotope with mass 150.9196 amu and 1-x represent the relative abundance of the other isotope with mass 152.9209 amu. The average atomic mass formula is [(mass isotope 1)(abundance isotope 1) + (mass isotope 2)(abundance isotope 2)] = average atomic mass. Substituting the values given, you can set up a system of equations and solve for x to find the relative abundance of each isotope.

Atomic mass represents the total mass of an atom, combining the mass of protons, neutrons, and electrons. Atomic number, on the other hand, is the number of protons in the nucleus of an atom, which determines its chemical properties and element identity.

The element with the greatest atomic mass is uranium.

Protons and neutrons are responsible for the atomic mass of an atom. Protons have a positive charge, while neutrons have no charge. The combined mass of protons and neutrons makes up the majority of the mass of an atom.

The atomic mass of ekasilicon is approximately 118.71 grams per mole.

Kripton is a non metal element. Atomic mass of it is 83.80.

It's quite simple. It's just the atomic mass minus the atomic number. That's because the atomic number is simply the number of protons and the atomic mass is (almost exactly) the number of protons plus neutrons. Unfortunately there is a complication.

The problem is that a particular element can have more than one isotope.

Each isotope has the same number of protons, but different numbers of neutrons. This can make the atomic mass a messy number that's not a nice whole number.

The atomic mass of aluminum is approximately 26.98 atomic mass units.

If the periodic table were arranged by atomic mass, some elements would be in a different order compared to the current arrangement by atomic number. This would mean elements with similar atomic masses would be grouped together, rather than by atomic number. The trends and patterns in the properties of elements might be less clear compared to the current layout based on atomic number.

I think you are asking for the mass of 0.35 moles of methane (CH4). First, we find the molecular mass of methane by addin the masses of all of the atoms. A carbon is 12, and each H is 1, so the molecular mass of CH4 is 16g/mole.

Now we multiply 0.35 moles by 16 g/mole. The moles cancel out, and we have 5.6 g.

For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n. * p = no. of protons. * n = no. of neutrons. Therefore, atomic mass of oxygen is 15.

Rn has 86 electrons, Th is the closest to having an atomic mass of 230

The atomic mass of the element with eight protons and nine neutrons is 17 atomic mass units. This is calculated by adding the number of protons and neutrons together, as electrons contribute negligible mass to the overall atomic mass.

The atomic number represents the number of protons in an atom, while the atomic mass represents the sum of protons and neutrons. Generally, the atomic mass is larger than the atomic number for most elements since it includes both protons and neutrons.

Atomic mass increases from top to bottom and left to right on the periodic table. In each row, the noble gasses have the highest atomic mass. As you travel down that column, also called a group or family, the noble gasses increase in atomic mass. The naturally occurring noble gas with the highest atomic mass is Radon (Rn; atomic mass = 211.4 amu).

In 2002, the unstable element Ununoctium was synthesized, and although it is a member of group 18, it was later determined to be a solid at room temperature, so it is not classified as a noble gas.

The average atomic mass of the element would be the average of the atomic masses of the three isotopes. Since they occur in equal amounts, the average atomic mass would be the sum of the atomic masses of the three isotopes divided by 3. This average atomic mass is a weighted average, taking into account the relative abundance of each isotope.

Basic arithmetic (5+6) suggests that the atomic mass is eleven.

Alcohol is a molecular compound made up of different elements such as carbon, hydrogen, and oxygen. Therefore, it does not have a single atomic number or atomic mass. The atomic number and atomic mass of the individual elements in alcohol (e.g., carbon, hydrogen, and oxygen) would need to be considered instead.

atomic mass unit (short: a.m.u.), symbol 'u', equiv. with (in S.I. units) 1.66054*10-27kg

The atomic mass number of an element is the sum of the number of protons and neutrons in its nucleus. To get the atomic mass number of 28.09, it typically corresponds to the average atomic mass of an element on the periodic table. For example, the element silicon has an average atomic mass of approximately 28.09, indicating that a silicon atom has an atomic mass number of around 28.
