Concept explainers
Interpretation:
The correct statements from the given set of statements should be given.
Concept introduction:
The
The same electronic configuration containing elements are arranged in the same group in periodic table. The vertical columns of the periodic table are known as families. The elements present in the column are said to be of the same family.
The
While naming a covalent compound, the first element is named first followed by the naming of the second element. If the first element exhibits more than one oxidation state then the current oxidation state being exhibited is to be mentioned.

- What are bus? How are ions formed from atoms? Do isolated atoms form ions spontaneously? To what do the termscationandanionrefer? In terms of subatomic particles, how is an ion related to the atom from which it is formed? Does the nucleus of an atom change when the atom is converted into an ion? How can the periodic table be used to predict what ion an element’s atoms will form?arrow_forwardWhat do we call reactions in which electrons are transferred between atoms or ions? What do we call a loss of electrons by an atom or ion? What is it called when an atom or ion gains electrons? Can we have a process in which electrons are lost by one species without there also being a process in which the electrons are gained by another species? Why? Give three examples of equations in which there is a transfer of electrons between a metallic element and a nonmetallic element. In your examples, identify which species loses electrons and which species gains electrons.arrow_forward2.30 Using Coulomb’s law, explain how the difference between attractive and repulsive interactions between ions in expressed mathematically.arrow_forward
