# Beanium lab report

Sort the atoms beans into a group for each isotope: black, brown, white. Complete the chart below: NAME a. Place all the beans back in the Ziploc bag.

### Isotopes and weighted average atomic mass

No other known element has atoms visible to the naked eye, or even to the most powerful optical microscopes. NOTE: All atoms of an element are isotopes of that element. The three different isotopes are blackium, brownium, and whitium. The weighted average atomic mass is calculated by multiplying the decimal equivalent of each isotope times its mass and adding up all the results for all the naturally occurring isotopes. They have a mass of 80 grams. Sort the atoms beans into a group for each isotope: black, brown, white. Record on the data table to the nearest 0. Write out the isotopic notation for each of the particles in 5. Find the mass of each individual isotope using a balance.

Place all the beans back in the plastic cup or ziplock bag. Determine the isotopic mass: a find the total mass of each of the three isotope groups and record on data table b find the average mass of a single atom of each isotope and record on the data table to the nearest 0.

### Isotopes and atomic mass lab beanium lab answers

What is an isotope? Obtain a sample of element Beanium. You are encouraged to refer to this document each time you write a lab report. Most elements have 1, 2 or 3 naturally occurring isotopes. Explain why the difference would be smaller if larger samples were used. Learning to write laboratory reports will provide you with a valuable and transferable skill. The average atomic mass of beanium was. NOTE: All atoms of an element are isotopes of that element.

Calculate the Percent abundance of red beans in the sample by dividing number of atoms of red beans by the total number of atoms in the sample. A source of error is an error that could have affected your results.

The sample contains atoms of three known isotopes of the element Beanium — red beans, navy beans whiteand pinto beans speckled. Record the total number of each isotope beans in your sample. Record the number of atoms in the data table below. Atomic masses are determined by comparing the mass of an atom to a standard mass, the mass of a carbon atom.

Beanium Lab 4 Isotopes and Weighted Average Atomic Mass If the atomic mass is the sum of protons and neutrons in an atom, why are the atomic masses on the periodic table not all whole numbers?

## What is an isotope

Determine the atomic mass of each isotope in the following manner. Sort the atoms beans into a group for each isotope: pinto, red, white. What does it mean to say that the atoms in a sample of an element are isotopes of each other? The average atomic mass of beanium was. Explain why the difference would be smaller if larger samples were used. The three different isotopes are pintonium, redium, and whitium. A source of error is an error that could have affected your results. Then you can calculate the "weighted average atomic mass" of Beanium. Remember significant digits for all calculations. Beanium Lab 2 Related documents. Refer to the table below for the different kinds or isotopes of two common atoms. Record the total number of atoms and the number of each type of isotope blackium, brownium, greenium and whitium in the data table. Explain why the difference would be smaller if larger samples were used.
