Answer:
1= Magnesium
2 = Option 3 = 1s² 2s² 2p⁶
Explanation:
An electrically neutral atom consist of equal number of protons and electrons.
The answer for 1st q is magnesium because the electronic configuration showed twelve number of electrons. The atomic number of magnesium is twelve that's why this configuration is of Mg.
Mg₁₂ = 1s² 2s² 2p⁶ 3s²
The second answer is option three because has atomic number ten and third electronic configuration have ten electrons.
Ne₁₀ = 1s² 2s² 2p⁶
It is stable electronic configuration. Neon is inert because of this electronic configuration. The outer most shell is completely filled.
Answer:
True
Explanation:
The desert refers to a region of arid land which is characterized by extreme temperatures, extreme dryness, low amount of precipitation and generally harsh living conditions. Because of these harsh conditions, they have been tagged with various names ranging from 'Death Valley' to 'the place from where there is no return' etc.
Every desert is made up of 2 components: the <u>biotic (living) component</u> and the <u>abiotic (non-living) component</u>. The biotic (living) component consists of the plants and animals that have adapted to these harsh living conditions e.g. Cactus or Cacti, Holly plants, Camels, Lizards, Snakes etc. The abiotic (non-living) component consists of climate (subtropical deserts which are extremely cold or temperate deserts which are extremely hot), location, precipitation/rainfall
