Cations are formed when atoms lose electrons, resulting in a net positive charge.
Generally, cations are formed by atoms of metals. Metals tend to have relatively low ionization energies, allowing them to easily lose electrons and form positively charged cations. Examples of metals that commonly form cations include sodium (Na⁺), calcium (Ca²⁺), iron (Fe²⁺ or Fe³⁺), and aluminum (Al³⁺), among others. It is important to note that not all metals form cations, as some metals can exhibit variable oxidation states or form anions in certain compounds.
Hence, Cations are formed when atoms lose electrons.

Answer:
positively charged atoms
Explanation:
What occurs during this reaction?
(1) Energy is absorbed as bonds are broken.
(2) Energy is absorbed as bonds are formed.
(3) Energy is released as bonds are broken.
(4) Energy is released as bonds arc formed.
Elements can be identified by their atoms through their atomic number, atomic mass, and chemical symbol, all of which are represented on the periodic table. The unique number of protons in an element's atomic nucleus is also identified. This information, combined with the arrangement of elements in the periodic table based on shared properties, reveals the identities of elements.
Elements are identified by their atoms through certain key properties that are represented on the periodic table. These key identifying properties include the atomic number, atomic mass, and the element's chemical symbol. For instance, in the case of carbon, its symbol (C) and name, its atomic number of six (given in the upper left-hand corner), and its atomic mass of 12.01 are displayed in its designated box in the periodic table.
Each element's unique number of protons in its atomic nucleus also helps identify an element. Additionally, the arrangement of elements in the periodic table provides insight into the elements' shared physical and chemical properties - they are arranged in a series of rows and columns based on these similarities. Atoms of elements can further combine and bond with each other in certain ways, based on these unique properties.
By the twentieth century, it was understood that these properties follow a periodic relationship with the atomic numbers, a concept referred to as the periodic law. A modern periodic table, thus, arranges the elements in ascending order of their atomic numbers and groups atoms with similar properties in the same column.

B. Carbon
C. Methane
D. Water
Carbon is the substance can not be decomposed by a chemical change. Therefore, option B is correct.
A chemical change is the transformation of one material into another, the formation of new materials with different properties, and the formation of one or more new substances. It occurs when one substance reacts with another to form a new substance.
Carbon and water Although carbon dioxide and carbonic acid are simpler compounds, they are still compounds. As a result, they can decompose and leave us with the basic elements' hydrogen, oxygen, and carbon. Compounds degrade due to chemical changes.
Elements are pure substances that cannot be broken down using conventional chemical methods such as heating, electrolysis, or reaction. Elements include gold, carbon, silver, and oxygen.
Thus, option B is correct.

Great question!
Physical changes change the appearance of something or someone.
For example, let's say 2 cats get into a fight. One is left clean in the end of this, with no scratches or bites anywhere, so nothing has happened to it as a physical change.
However, the other cat is left scarred and with bite marks everywhere. All this has left the cat's once-beautiful coat now ragged and torn up. This is an example of a physical change.
