Which 3 atomic properties will you examine for periodic trends?
For periodic trends we will examine1- Electronic configuration 2- Ionization energy 3- Atomic radius
What are 2 reasons for studying the periodic table?
Periodic table of elements provides us a lot of information about element's intrinsic properties. We can get the atomic weight of an element by looking at the periodic table. Trends about the electronegativity and atomic size can also be computed.
What periodic trends did did Mendeleev organize his periodic table by?
Atomic Mass Octaves and Triads
What periodic trends did Mendeleev organize his periodic table by?
atomic mass, triads, and octaves
What trends were seen in Mendeleev's periodic table?
he arranged his Periodic Table by each elements Atomic Mass
What are periodic trends?
periodic trends are the tendencies of certain elemental characteristics to increase or decrease as one progresses along a row or column of the periodic table of elements.
What 2 atomic properties will you examine for periodic trends?
- atomic number (number of protons)- electron configuration
What periodic trends are inversely proportional to effective nuclear charge?
atomic radius
When you go across the periodic table how does the atomic size go?
Atomic size decreases across the rows of the periodic table
Atomic mass trends in the periodic table?
Atomic Mass increases in size as the atomic number increases. For example, hydrogen weighs about 1.01 grams per mole and it has periodic #1. Helium is atomic #2 and it has an atomic mass of 4.00 g/mol. This trend continues all the way to the last known pure element.
What are names of the trends in the periodic chart?
Atomic size decreases from left to right in a period hence ioniztion energy increases from left to right.But atomic size increases from top to bottom in a group hence ionization energy decreases from top to bottom.
What are three periodic trends you encounter in your life?
Seasons: The changing of seasons, like summer, fall, winter, and spring, is a recurring pattern we encounter each year. Lunar cycles: The phases of the moon, such as full moon and new moon, occur in a regular cycle. Paychecks: For many people, receiving a paycheck on a bi-weekly or monthly basis is a periodic trend that impacts their financial planning.
