Explanation: The element with atomic number 20 consists 20 electrons and as atomic number is specific to an element, atomic number is of element calcium.
The nearest noble gas to calcium is argon with 18 electrons with configuartion according to afbau's rule, in which orbitals are arranged in order of increasing energies.
Thus electronic configuartion of calcium in terms of noble gas configuration is:
B. An atom is entirely solid and has no empty spaces between its particles.
C. An atom has a dense nucleus surrounded by mostly empty space where electrons travel.
Water (H₂O) is an example of a covalent bond, where hydrogen and oxygen atoms share electrons to form a molecule. It is also a polar molecule and commonly acts as a solvent. Water is central in various scales of biological and environmental structures and processes.
Water, or H₂O, is an example of a covalent bond formation. This occurs when hydrogen and oxygen atoms join together, sharing electrons to fill their outer shells and create stability. This sharing of electrons forms a water molecule.
Furthermore, water is considered a polar molecule. Aside from covalent bonding, another characteristic of water is its ability to act as a solvent. It can dissolve gases, liquids, and solids to create different solutions, which is vital in many biological and chemical processes.
A representation of this can be seen from a hydrogen atom, to a water molecule, skin cell, liver, larger organisms like an elephant, wolf pack, up to larger ecosystems like tropical rainforests and the entire planet Earth, indicating the wide scope where water plays a crucial role.
