True False

Answer 1

Question 1

Electro negativity describes the ability of an atom to repel electrons.

		False

Electro negativity is the ability to attract bond pair to wards it

Question 2

Atomic radius increases as you move down a group of elements.

True

Down the group valance electron enters into new sub shell. So size increases

Question 3

The bottom left-hand corner of the periodic table contains elements with the highest electron affinity values.

False

They are electro positive elements

Question 4

The distance from the center of the atom to the average position of the outermost electrons is referred to as the atomic mass of the element.

True

Question 5

A Ca²⁺ ion is smaller in size than a neutral Ca atom.

True

As +ve charge increases size decreases so Ca+2 is smaller size than Ca atom

Question 6

Which of the following atoms would possess the largest atomic radius?

francium

Question 7

Which of the following possesses the highest first ionization energy value?

		fluorine
		chlorine
		oxygen
		sulfur

Answer: Due to its small size fluorine has high first ionization

Question 8

Which elements have their highest energy electrons in "s" atomic orbitals?

		H, He, Ne
		O, Se, Po
		Na, Sr, Fr
		Cs, Hf, Tl

Na, Sr, Fr : their valance electron configuration is      nS¹

Question 9

The 57th electron in an atom's electron configuration will be placed into which orbital?

		5d
		6d
		4f
		6p

Answer: 5d

Question 10

Every element whose symbol appears in Group 14 of the periodic table has an electron configuration that ends in "…p²."

		True
		False

True

Question 11

Transition metal elements are in the "d block" on the periodic table, because the electron configuration of every transition metal ends with electrons in "d" atomic orbitals.

True
