i have no clue what so ever sorry
Answer:
52.068 amu
Explanation:
To calculate the average atomic mass of chromium, you have to first multiply the abundance of an isotope with its mass.
49.946 × 0.0435 = 2.173
51.941 × 0.838 = 43.527
52.941 × 0.0235 = 1.244
53.939 × 0.095 = 5.124
Next, add up all of the values, and you will get the average atomic mass.
2.173 + 45.527 + 1.244 + 5.124 = 52.068 amu
Sulfur and sodium are those two elements
Explanation:
Ionic bonds are bonds formed as a result of the electrostatic attraction between two species.
- This bond type is an interatomic bond.
- It forms when two specie with a large electronegative difference between them combines.
- This is usually a metal and a non-metal.
- The metal loses its valence electrons and becomes positively charged.
- The non-metal gains the electron and becomes negatively charged.
- An electrostatic attraction between the two specie leads to the formation of an ionic bond.
- They are solids with a high melting point.
- They are soluble in polar solvents.
