Answer: Option (c) is the correct answer.

Explanation:

Electronegativity is defined as the ability of an atom or element to attract the electrons from another atom towards itself.

Non-metals are the species which are electronegative in nature. Whereas metals are the species which are electropositive in nature.

For example, F, l, Br and I are group 17 elements. These are electronegative in nature but their electronegativity decreases from fluorine to I.

Whereas Li, Na, K are alkali metals and most electropositive in nature.

Similarly, Be, Mg, Ca are group 2 elements and they are also electropositive in nature. When we move from top to bottom in a group then there is a decrease in electronegativity of the non-elements.

But when we move from left to right in a period then due to decrease in size of the atoms there will be increase in electronegativity of the atoms.

Thus, we can conclude that K, Ca, Sc list of elements is arranged in order of increasing electronegativity.

k0ka [10]

The volume of the textbook calculated by the student written to 3 significant figures is 992cm³

  • According to this question, a student calculates the volume of his textbook and arrived at an answer of 991.880 cm³.

  • To round up this digit to 3 significant figures, which means that only 3 significant numbers should appear in the answer.

  • To do this, the number after the third number is 8, which means we can round up the value of 1 to 2. Hence, the volume of the textbook calculated by the student is 992cm³ in 3 s.f.
