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
Periodic Table - Or Table of Reactivty
No it decreases.
The reactivity increases with increasing numbers of electron shells (energy levels).
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
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.

Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
A periodic table predicts the properties and behavior of elements based on their atomic structure, such as atomic number, electron configuration, and chemical reactivity. It can be used to determine trends in properties like atomic size, electronegativity, and reactivity, aiding in understanding and predicting the behavior of elements in chemical reactions.
