To provide accurate answers, I would need specific clues or questions from your Periodic Table and reactivity crossword. However, common themes in such puzzles might include element symbols, reactivity trends (like metals vs. nonmetals), or specific elements known for their reactivity, such as alkali metals (like sodium or potassium) and halogens (like chlorine). If you provide more details or clues, I can help you better!
Since we have no idea what "the periodic table crossword" means, we cannot answer this question.
Decrease reactivity
The term "castle Mendeleev" likely refers to a crossword clue related to Dmitri Mendeleev, the Russian chemist known for creating the periodic table. Common crossword answers might include "SODIUM" (Na) or "TABLE," depending on the specific clues provided. If you have a specific crossword puzzle in mind, please provide more context or clues for a more accurate answer.
Periodic Table - Or Table of Reactivty
No it decreases.
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
The reactivity increases with increasing numbers of electron shells (energy levels).
a Periodic Table organises the different elements, according to the atoms' mass, type, properties, reactivity etc. See the question about: periodic table patterns
Chemical reactivity first decreases.then it increases as we move across a period.
Reactivity is associated with position. Chemical properties of element can be determined from its position.
