It is important to use a weighted average because different isotopes of an element have different atomic masses due to the presence of different numbers of neutrons. The abundance of each isotope also varies, meaning some isotopes are more common than others. By using a weighted average, the more abundant isotopes have a greater contribution to the overall average atomic mass of the element, providing a more accurate representation.

The average atomic mass number of Krypton is approximately 83.8 atomic mass units.

The atomic mass of tin is approximately 118.71 atomic mass units.

The actual weight of a regular pear would be about 4 ounces.

You can convert molecules to mass easily using the fact that there are 6.022*10^23 molecules in a mole of an substance. Convert your molecules to moles, then use the molar mass of your substance to determine the mass.

We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.

Magnesium (Mg) is part of the alkaline earth metals.

Psalms 95:6 O come, let us worship and bow down: let us kneel before the LORD our maker. Daniel 6:10 Now when Daniel knew that the writing was signed, he went into his house; and his windows being open in his chamber toward Jerusalem, he kneeled upon his knees three times a day, and prayed, and gave thanks before his God, as he did aforetime Matthew 28:18 And Jesus came and spake unto them, saying, All power is given unto me in heaven and in earth. Romans 11:4 But what saith the answer of God unto him? I have reserved to myself seven thousand men, who have not bowed the knee to the image of Baal. Philippians 2:10 That at the name of Jesus every knee should bow, of things in heaven, and things in earth, and things under the earth;

The same as for a helium nucleus: 4. Two protons and two neutrons.

12 protons 14 neutrons

Atomic mass is the number of protons present in the nucleus or number of electrons revolving around the nucleus in an atom .It is denoted by Z.

Mass number is the sum of number of protons and neutrons present in a nucleus in an atom .It is denoted by A.

The measurement of mass is usually kg(kilograms) for large masses and g(gram) for small masses.The word kilo means 1000 so it's just another way to say 1000 grams. You can also use mg(milligrams). Mill means thousandths. So if you put that in a decimal it would be 0.001. So a 1000mg=1 gram.

Molar mass is the weight of one mole of any chemical compounds. Atomic mass is the weight of just 1 atom of a compound

The atomic mass and the relative abundance of each naturally occurring isotope of chlorine.

By taking the wieghted averages of naturally occurring isotopes of that element. :)

the atomic mass is the atomic weight. look at your periodic table and you will find its 83.8 which is 84

you go to the land of mordor and drop the one ring into the fires of mount doom

the Atomic Mass number is the number of protons/electrons in an atom

Yes, Neon (Ne), a noble gas; the atomic weight (IUPAC 2005) is 20,1797 ± 0,0006. For the elements the expression atomic weight is accepted as correct after the traditional definition of IUPAC (International Union of Pure and Apllied Chemistry).

Mass is a measure of the resistance of an object to changes in velocity, as described by Newton's Second Law, F=ma (weight is the force generated when the acceleration is due to gravity).

The reference standard for mass is the International Prototype Kilogram, so you could use a set of scales to compare your object to that. You could measure the extension of a spring with the object hanging from it, knowing how much a spring extends normally (Hooke's law).

If you found yourself somewhere without gravity, you could spin the object round on the end of a rope and measure the force it takes to keep it in a circle, or attach a rocket which provides a known amount of thrust.

As a cataclysmic alternative, you could fire antimatter at the object until it was entirely destroyed, and measure the energy released using E=mc2 to find the mass destroyed, which will be your object and an equivalent mass of antimatter.

The element with the atomic number 120 is theoretical and hasn't been observed. However, it does still have a systematic IUPAC placeholder name - Unbinilium (Ubn). No attempts have ever been made to create this element. If it were to be discovered, it would fit in under Radium as an Alkaline Earth Metal.

Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.
