Chemistry Of The Elements -

: The tendency of an atom to attract electrons increases as you move toward the top right (excluding noble gases).

: The energy required to remove an electron increases as you move toward the top right. Chemical Bonding

Elements are categorized into groups (columns) and periods (rows) that share similar characteristics: Chemistry Of The Elements

Each element is defined by its , which is the number of protons in its nucleus. This fundamental value determines the element's identity and its position in the periodic table. The chemistry of an element is primarily driven by its valence electrons —the electrons in the outermost shell—which dictate how it bonds with other atoms. Major Groups and Trends

: One atom "steals" electrons from another (e.g., Sodium and Chlorine forming Salt). : The tendency of an atom to attract

: Located in Group 18, these elements are highly stable and rarely react with others because they have a full set of valence electrons. Periodic Trends

As you move across or down the table, specific chemical behaviors follow predictable patterns known as periodic trends: This fundamental value determines the element's identity and

: The size of an atom generally increases as you move down a group and decreases as you move left to right across a period.
