11. Ano ang tawag sa mga islang matatagpuan sa Pacific Ocean?
a. Australia
b. Oceania
c. Antarctica​

Answer 1

Explanation:

The electron configuration of a neutral calcium atom is : 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 . A calcium 2+ ion has lost its two valence electrons, and now has 18 electrons. Thus the electron configuration of a Ca^2+ ion is : 1s^2 2s^2 2p^6 3s^2 3p^6 , which is isoelectronic with the noble gas argon.

Answer 2

Answer:

Australia

Oceania is a region made up of thousands of islands throughout the Central and South Pacific Ocean. It includes Australia, the smallest continent in terms of total land area.
