Concept explainers
(a)
Interpretation:
Whether the elements become more metallic or less metallic on moving down a group in the periodic table is to be stated.
Concept introduction:
Those elements that have tendency to form positive ion by losing electrons are called metals. So, metals are electropositive elements. The elements that have tendency to form anions by gaining electrons are called nonmetal. So, nonmetals are electronegative elements.
(b)
Interpretation:
Whether the elements become more metallic or less metallic on moving left to right across a period in the periodic table is to be stated.
Concept introduction:
Those elements that have tendency to form positive ion by losing electrons are called metals. So, metals are electropositive elements. The elements that have tendency to form anions by gaining electrons are called nonmetal. So, nonmetals are electronegative elements.

- 2.42 What is a period in the periodic table? From what does it derive its name?arrow_forward2.84 Early attempts to arrange the elements often focused on atomic weight. Mendeleev considered a number of properties in addition to atomic weight, so he realized that some elements seemed out of place when ordered by atomic weight. Using the modern periodic table, identify elements for which Mendeleev must have had to switch the order in order to get the correct sequence of elements.arrow_forwardOne of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. Does this apply to Daltons atomic theory? Give examples.arrow_forward
