Transition metals
Most transition metals differ from the metals of Groups 1, 2, and 13 in that they are capable of forming more than one cation with different ionic charges. As an example, iron commonly forms two different ions
Allelopathy, the pine needles make the ground more acidic so weeds cannot grow and steal nutrients the tree needs
Consumption of the acidic and the basic is equal during human's life. For example, acidic ones add sourness to things we eat and what about basic - the taste is quite bitter that conidered to be less enjoyable. Every our dish consists of both listed elements but our bodies are already accustomed to this fact.
Hope that helps.
Answer:
atoms are neutral or they have equal number of proton and electron but ions can be cation(positively charged) or anion(negatively charged) based on the number of electron the atm lose and gain respectively
<span>Because protons and neutrons are so much more massive than electrons, almost all of the atomic mass in any atom comes from the nucleus, which contains all of the neutrons and protons.</span>
