Atoms
Atoms are the basic building block of what?
Everything/all matter.
This element contains 20 protons.
Calcium
This is the number of protons in the nucleus of each atom of an element
Atomic number
This element has the highest electronegativity.
Fluorine
Which type of orbital is peanut-shaped?
P orbital
This is a particle with no charge found in the nucleus of an atom.
Neutron
These are shiny, good conductors of heat, and have luster.
Metals
The vertical columns on the periodic table are called what?
Groups
This trend increases as you move down a column on the periodic table.
Atomic radius/number of energy levels
How many electrons can fit in one orbital?
2 electrons
This is an atom with a charge.
Ion
These are elements that have characteristics of metals and nonmetals.
Metalloids
Nonmetals
Ionization energy increases moving from left to right across a row on the periodic table due to this.
Increasing number of protons, number of energy levels remains the same.
What does the number in front of the letter in an electron configuration represent?
The energy level
These are atoms of the same element that have a different number of neutrons.
Isotopes
These elements are unreactive and have a full outer shell of electrons.
Noble gases
This is the sum of the an atom's protons and neutrons
Mass number/atomic mass
Effective nuclear charge
What is the noble gas configuration for lithium?
[He]2s^1
A phosphorus ion has this charge.
-3
These are elements that are man-made and are not naturally occurring.
Synthetic elements
This element is in period 5 on the periodic table and forms a +2 ion.
Strontium
How does the size of a magnesium ion compare to the size of a neon atom?
Magnesium ion is smaller
How many total p orbitals does silicon have?
5
