1. Vertical columns in the periodic table indicate groups and families. These are groups of elements with similar properties, such as the alkali metals in Group 1 or the halogens in Group 17.

2. Families of elements include metals and noble gases. Families are groups of elements with similar properties, such as metals having high conductivity and noble gases being chemically inert.

3. The atomic mass of many elements is not a whole number because an element may have isotopes with different numbers of neutrons. Isotopes are atoms of the same element with different mass numbers due to varying numbers of neutrons.

The narrator of Pit and the Pendulum wrote the physical details of the prison and the torments endured by a prisoner. This uncertainty suggests that the narrator is traumatized and desperate.

What is the idea of "The Pit and the Pendulum?"

"The Pit and the Pendulum" is a short horror story by Edgar Poe. It is about the torture tolerated by a prisoner. The story surrounds death and time, the death sentence to the narrator is like a shock though he thinks it is better than enduring torture. But in the end, the narrator tries to fight and live.

In the story, the narrator is desperate and has an intense desire for routes to escape his death. He wanted to forget the torturous exposure to prison and does not want to go insane from all the trauma.

Therefore, the narrator is uncertain about time.

Answers

The answer is 'b' The Delaware River not only borders Philadelphia but also divides Pennsylvania and New Jersey
