The statement “Ionic crystals are extremely malleable because they contain a positively charged metal ion” is false. Ionic crystals are composed of positive and negative ions that are combined so that the numbers of positive and negative charges are equal.
b. neutral
c. basic
d. there is not enough information to answer the question
Answer:
b
Explanation:
on edge
B. an increase in atomic radius and an increase in electronegativity.
C. a decrease in atomic radius and a decrease in electronegativity.
D. an increase in atomic radius and a decrease in electronegativity.
E. None of these answer choices is correct.
There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Therefore, the correct option is option A.
Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can discover the new elements that are not being discovered yet.
Within a period, an increase in atomic number is usually accompanied by a decrease in atomic radius and an increase in electronegativity.
Therefore, the correct option is option A that is a decrease in atomic radius and an increase in electronegativity.
