What are dot diagrams

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.)

Which of the following elements has the highest electronegativity

Al, Ca, H, or K?

What does the electronegativity of an atom indicate

the tendency of the atom to pull on electrons Apex : )

How could an electron configuration be used to predict relative atomic size

the larger the highest energy level number, the larger the atomic radius

What trend does electronegativity follow going down the periodic table

Electronegativity decreases because the valence electrons are farther from the nucleus.

What makes the atomic radius change down a column of the periodic table

The larger the highest energy level, the larger the atomic radius.

What kind of bond is made up of shared electrons

covalent bond

How does a full octet affect trends among the noble gases

A full octet makes the noble gases nonreactive.

What trend does the first ionization energy follow going across the periodic table

The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.

What trend does the atomic radius follow along a period on the periodic table

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.

What trend does the first ionization energy follow going down the periodic table

The first ionization energy decreases because the outermost electron is farther from the nucleus.

Apex

What makes the atomic radius change along a period in the periodic table

More protons in the nucleus pull the electrons in, making the atomic radius smaller.

Which of the following elements shows little reactivity Fluorine Sulfur Potassium or Argon

From the elements given, argon shows the least reactivity.

Which values best classifies a bond between 2 atoms as being ionic

The values that best classifies a bond between 2 atoms as being ionic are the valence electrons.

Which of following elements has the largest first ionization energy

Strontium (Sr) Apex

What of the following elements potassium iron or aluminum is the the most reactive and explain

Potassium is the most reactive because has the highest electronegativity.

Which of the following elements has the lowest electronegativity ba ca mg sr

Barium(Ba)

Which of these molecules is nonpolar

O2

What elements has the least reactive metal

magnesium (Mg)

Which of the following elements is the smallest

question: which of the following elements is the smallest?

answer: chlorine (CI)

which of the following elements is the largest

Boron
