Answer: Option (D) is the correct answer.
Explanation:
Atomic number of lithium is 3 and electrons in its shell are distributed as 2, 1. Atomic number of chlorine is 17 and electrons in its shell are distributed as 2, 8, 7.
Thus, we can see that lithium has 1 extra electron and chlorine has deficiency of 1 electron. Therefore, in order to gain stability lithium will transfer its 1 extra electron to chlorine atom.
Thus, we can conclude that electrons are transferred from the lithium atom to the chlorine atom.
Basaltic Rocks
Basaltic Rocks
The top layer of the sea floor is primarily composed of about 50 % basalt, which is the most common type of volcanic rock to be erupted.
Both igneous and sedimentary rock types can transform physically and chemically into a third rock type. Metamorphic rocks are formed when igneous or sedimentary ... Basalt
Granite is a common intrusive rock in continents. If magma with the same composition reaches the surface, it forms extrusive rocks such as rhyolite and pumice (PUHM-ihs). Basalt (buh-SAWLT) is an extrusive igneous rock that forms the ocean floor. Gabbro is an intru- sive rock that has the same composition as basalt.
Answer:
The pitch of a sound is related to its frequency.
Explanation:
The higher the frequency, the higher the pitch will be
Amplitude is related to how loud a sound is
Answer: B. Elements are represented by chemical formulas.
Elements are pure substances, which means that they cannot be broken down into simpler substances. The element is the most basic substance that exists, breaking it down further means breaking it down into protons, neutrons, and electrons, which is no longer a substance.
Elements have chemical properties that allow them to form different types of bonds with other elements.
However, elements *alone* are not represented by their chemical formulas. Only chemical bonds or ions are represented by a chemical formula.
