Answer:
D. They have the same number of protons as electrons.
Explanation:
Protons are found in the nucleus of the atom and have a positive charge while electrons orbit around the nucleus and have a negative charge. Usually, in a neutral atom of an element, the number of protons is equal to the number of electrons. This is why the atom has no charge because the positive and negative charges cancel out. When an atom loses an electron its charge turns positive while when it gains an electron its charge turns negative.
An Arrhenius acid is a substance that dissociates in water to form hydrogen ions (H+). In other words, an acid increases the concentration of H+ ions in an aqueous solution. This protonation of water yields the hydronium ion (H3O+); in modern times, H+ is used as a shorthand for H3O+ because it is now known that a bare proton (H+) does not exist as a free species in aqueous solution.
Answer:
It can recognize several distinct flavor profiles: salty, sweet, sour, bitter, and umami — aka savory. Now, research suggests a sixth type of taste receptor on the tongue is responsible for people and animals being able to determine the taste of water among other fluids
(1) Ar is your answer. Argon is a noble gas, which is stable in its standard valence electron configuration because it already completed its valence shell following the octet rule.
It is purely called the Atomic Mass
