Ionic crystals are extremely malleable because they contain a positively charged metal ion,TRUE

FALSE

Answers

Answer 1
Answer:

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.

A rigid framework of many ions locked together in a repeating pattern is called a(n)

Answers

A crystal is rigid framework of many ions locked together in a repeating pattern.A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

An unknown solution has a ph of 8. how would you classify this solution? a. acidic
b. neutral
c. basic
d. there is not enough information to answer the question

Answers

I believe the correct answer from the choices listed above is option C. You would classify this solution as basic since it has the pH of more than 7 which signifies a basic solution. Hope this answers the question. Have a nice day. Feel free to ask more questions.

Which set of numbers gives the correct possible values of l for n = 2? 0 0, 1 0, 1, 2 0, 1, 2, 3

Answers

The answer is 0 and 1

This is because for a given principal quantum number, n, the corresponding set of angular quantum numbers, l, is equivalent to a range between 0 and (n-1). For n=2, (n-1) is equal to 1, so the range is 0 and 1. The magnetic quantum number, m, can be determined by a range from -l to +l. So for this example, m = -1, 0, 1.

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.

What is periodic table?

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.
