Electronegativity, electron affinity, nonmetalic nature, acidic nature of oxides, valency with respect to oxygen ( from 1 to 7), number of electrons in the outer most shell ( 1 to 8) increases across a period from left to right

What periodic trends did Mendeleev organize his periodic table by?
atomic mass, triads, and octaves
Does sodium have a smaller atomic radii than sulfur?
The atomic radius of Na is greater than that of Si because as you move to the right across the periodic table there are more electrons which cause more attraction between the protons and electrons which cause them to pull closer together.
Atomic size generally as you go down a group?
Atomic size generally increases as you go down a group
What is the periodic trend for atomic size from top to bottom in a group?
The size of an atom refers to its atomic radius. Atomic radius generally increases down a group. This is because the number of energy levels increase down a group with each additional period. Each of the subsequent energy levels are larger than the last, increasing the distance of the electrons from the nucleus, which increases the atomic radius.Atomic radius generally decreases across a period. This is because electrons are being added to the same energy level at the same time that protons are being added to the nucleus. This creates a stronger force of attraction by the nucleus for the electrons, which pulls the electrons closer to the nucleus, decreasing the atomic radius.It is important to note that the periodic trends are not laws. There are exceptions to the general trends in both the representative elements and the transitional elements.
What physical trends for atomic number versus covalent radius?
Overall as atomic number increases covalent radius increases.
What trends do you notice about the atomic number and atomic mass as you move left to right across the periodic table?
The atomic number increases from left to right. The atomic number also increases.However, there are few exceptions for atomic mass.
What are the general trends andpatterns within the periodic table?
Atomic radius increases down the group. It decreases along a period.
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
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.
Which 3 atomic properties will you examine for periodic trends?
For periodic trends we will examine1- Electronic configuration 2- Ionization energy 3- Atomic radius
Why is the periodic table useful for studying the properties of different elements?
well, the periodic table is very useful because you have the atomic number, atomic mass, and even the trends across a period or down a group.
What periodic trends did did Mendeleev organize his periodic table by?
Atomic Mass Octaves and Triads

What are two trends in the periodic table?
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.
