Neon (Ne) is in group 18 and period 2. Which of the following is true?
Neon is a noble gas.
Neon doesn't react with other elements under normal conditions.
Neon has two electron shells.
Neon is part of the metal group.
Neon is a gas under normal conditions.

Respuesta :

Neon is a noble gas.

True

Neon doesn't react with other elements under normal conditions.

True

Neon has two electron shells.

True

Neon is part of the metal group.

False => Noble Gas or Non-metal group

Neon is a gas under normal conditions.

I'd say true considering it is a gas.

Answer:

Neon(Ne):

Its an inert element placed in group 18 and period of the periodic  table. The element comes in the; category of Noble gases, it means that the atom does not react with any other atom under normal conditions.

Properties of Neon(Ne):

  • Atomic Number - 10,
  • Atomic weight- 20.183,
  • Melting point- -248.67°C,
  • Boiling Point- -246°C,
  • There are about 12 radioactive isotopes of the element,
  • Electronic Configuration - 1s²2s²2p⁶.

Explanation:

  1. Neon is a noble gas- True it is a noble gas.
  2. Yes, it does not react under normal conditions given as the electronic configuration of the element satisfies all the condition.
  3. The electronic shells are two in number the first shell has 2 electrons in its boundary, while the second shell consists of 8 in its shell.
  4. False, Neon is not a metal. It comes in the non metal or more over Nobel gases group.
  5. Neon's extreme point gives it a more gaseous nature and as it exists in the form of as a colorless, odorless and more lighter element.
