1)   How many new elements were added to the Periodic Table by the IUPAC in 2016?

A) 5

B) 3

C) 4

D) 7

In late 2015–2016 IUPAC formally accepted the discovery claims for four superheavy elements and approved their names in 2016. These four additions were:

Element 113 — Nihonium (Nh)

Element 115 — Moscovium (Mc)

Element 117 — Tennessine (Ts)

Element 118 — Oganesson (Og)

Ans)  C) 4


2)  Having an ugly or displeasing sound

A) Cacophonous

B) Eternal

C) Glutton

D) Impeachable

Cacophonous (adj.) means harsh, discordant, or unpleasant-sounding — from Greek kakophōnos (kakos = bad + phōnē = sound/voice). Example: The cacophonous honking made the meeting impossible to hear.

Eternal means lasting forever; glutton is a person who overeats; impeachable means capable of being charged with misconduct. None of these match the meaning “having an ugly or displeasing sound.”

Ans)  A) Cacophonous
