There are two types of diagrams one is the Lewis diagram the other is the Electron dot diagram. To make the electron dot diagram you put the electron symbol and put a dot on one of the sides for each period (you don't count the middle section.)
:Ne: = Neon dot diagram
Al, Ca, H, or K?
the tendency of the atom to pull on electrons Apex : )
the larger the highest energy level number, the larger the atomic radius
Electronegativity decreases because the valence electrons are farther from the nucleus.
The larger the highest energy level, the larger the atomic radius.
A full octet makes the noble gases nonreactive.
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
The atomic radius gets smaller the farther right it appears on the periodic table, until the addition of a new orbital increases the size again.
The first ionization energy decreases because the outermost electron is farther from the nucleus.
More protons in the nucleus pull the electrons in, making the atomic radius smaller.
From the elements given, argon shows the least reactivity.
The values that best classifies a bond between 2 atoms as being ionic are the valence electrons.
Strontium (Sr) Apex
Potassium is the most reactive because has the highest electronegativity.
question: which of the following elements is the smallest?
answer: chlorine (CI)
