- Some questions frequently asked by houseowners : periodic table trends?
♥ what is the trend in both ionization and electronegativity? (on the periodic table)what are the periodic table trends?
♥ i have an exam on monday, and my teacher hasn't explained it very well. is it true that: groups: atomic radius increases going down the group alkali metals reactivity increases going down the group halogen reactivity decreases going down the group metals lose valence electrons more easily going down the group (therefore they are more metallic) from group i to iii metal reactivity decreases periods: oxides become more acidic going left to right atomic radius decreases going left to right it is harder to lose valence electrons going left to right (therefore the atoms are becoming less metallic) thanks! thank you so much!question about ionization energy periodic table trend ?
♥ my practice pcat book has a question: which property does the following period trend describe- the property rises to a maximum around the middle of the period and then falls off the a minimum value at the end of the period (excluding the first period). in the second period, carbon has the maximum value for this property and in the sixth period, tungsten has the maximum value. a) denisty b) melting point c) electronegativity d) ionization potential. the book says the answer is d, however all other sources online says otherwise, including looking up the actual numbers for ionization potentials - http://web.mit.edu/course/3/3.091/www3/pt/pert9.html. i am very confused. thanks! waldo- you'd be surprised to know that this question was taken directly from the practice pcat tests created by pearson (the company which administers the pcat). this question is from their website. and, it is their answer key that provided the answer as being ionization potential. also, there was no associated graph, just the information i provided.what are the trends of the periodic table?
♥ what are the trends in the periodic table?
♥ eg size of the atoms decrease as you move across the period in the periodic tabl.
