arrange the following elements in order of increasing atomic mass; Cu, C, K, H, F, Cl, Xe, Cr, Pb, Na
To arrange the given elements in order of increasing atomic mass, you will need to look up the atomic masses of each element and compare them.
1. Start by looking up the atomic masses of the elements:
- Cu (Copper) = 63.55
- C (Carbon) = 12.01
- K (Potassium) = 39.10
- H (Hydrogen) = 1.01
- F (Fluorine) = 18.99
- Cl (Chlorine) = 35.45
- Xe (Xenon) = 131.29
- Cr (Chromium) = 52.00
- Pb (Lead) = 207.2
- Na (Sodium) = 22.99
2. Now, arrange the elements in ascending order according to their atomic masses:
- H (1.01) < C (12.01) < Na (22.99) < F (18.99) < Cl (35.45) < K (39.10) < Cr (52.00) < Cu (63.55) < Pb (207.2) < Xe (131.29)
The elements arranged in order of increasing atomic mass are:
H, C, Na, F, Cl, K, Cr, Cu, Pb, Xe
To arrange the given elements in order of increasing atomic mass, we need to compare the atomic masses of each element.
Here is the list of elements in increasing order of atomic mass:
1. H (Hydrogen) - Atomic Mass: 1.008
2. Xe (Xenon) - Atomic Mass: 131.293
3. F (Fluorine) - Atomic Mass: 18.998
4. Cl (Chlorine) - Atomic Mass: 35.453
5. C (Carbon) - Atomic Mass: 12.01
6. Na (Sodium) - Atomic Mass: 22.99
7. K (Potassium) - Atomic Mass: 39.098
8. Cu (Copper) - Atomic Mass: 63.546
9. Cr (Chromium) - Atomic Mass: 51.996
10. Pb (Lead) - Atomic Mass: 207.2
So, the elements arranged in increasing order of atomic mass are:
H < Xe < F < Cl < C < Na < K < Cu < Cr < Pb
Why don't you look at the periodic table, find the element and the atomic mass of each element and arrange them. Don't have a periodic table? Here is one.
