4. Write the charge of each ion. Here are some other examples of dot and cross diagrams for the formation of ions in some ionic compounds – magnesium oxide and calcium chloride.

The attraction by chlorine is stronger than the attraction by sodium. An electron is transferred from sodium to chlorine. Sodium becomes a positive ion and chlorine becomes a negative ion. The ...

Add 0.1M KSCN solution to beaker #3. The color should again become more intense with the formation of additional complex. Add 1M NaOH dropwise to beaker #4. The color should become less intense as ...

A new study provides fresh insight into traditional acid-base chemistry by revealing that the mutual neutralization of ...

The pioneering nuclear chemist Glenn Seaborg discovered berkelium at Berkeley Lab in 1949. It was one of many achievements ...

Conventional preparation techniques use chemical attacks to remove remnant ... that could be used to shed light on the formation of charged ion-conductive gels in the tracks.

Now, a host–guest system has been built that responds to the addition of metal ions, showing promise for drug-delivery applications. Figure 1: Supramolecular capsule formation between cucurbit[7 ...

Unsubstituted π-electronic systems with expanded π-planes are highly desirable for improving charge-carrier transport in ...

The pioneering nuclear chemist Glenn Seaborg discovered berkelium at Berkeley Lab in 1949. It was one of many achievements related to transuranium elements that led to his winning the 1951 Nobel Prize ...

Scientists have discovered “berkelocene,” the first organometallic molecule to be characterized containing the heavy element berkelium. The breakthrough disrupts long-held theories about the chemistry ...
