The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
<h2>
Heat emission by stars.</h2>
Explanation:
The given statements summarize to the following points -
- Electromagnetic radiation is measured in arrange to recognize components of space which is not visible optically, such as the sum of warm a star is radiating or heat emitted by the stars.
- Cosmologists utilize the complete electromagnetic range to watch a different type of thing related to the planet or outer space bodies.
- Radio waves and microwaves – the longest wavelengths and least energies of light – are utilized to peer interior thick interstellar clouds and track the movement of cold, dim gas.
- During the carbon cycle, the carbon is transferred across the biosphere. Plants change over CO2 to oxygen and glucose through photosynthesis. Carbon is a chemical component, like hydrogen and oxygen. Carbon is present in all living things – such as creatures and plants or the biotic component – as well as the ocean, soil, and rocks or the abiotic component. Carbon dioxide is a gas made up of the components of carbon and oxygen. Hence, the other elements that should be present are oxygen and hydrogen that will make other planets similar to that of earth.
Answer:
8.50g of NH3 is present in 250ml volume .
1. An ionic bond is an attraction between oppositely charged ions. A covalent bond is sharing of electrons between atoms.
2. A bond between two atoms
3. covalent bond
4. They have different properties because the arrangement of atoms is different.
5. Mutual attraction between the nuclei and electrons in two different atoms
