How many protons does an atom of tin have?
The answer is 50, which also means that a neutral atom of tin will have 50 electrons.
What determines the way an atom behaves?
The way electrons are arranged in the electron cloud.
What is the energy level of an electron indicated by?
The large numbers in the diagram.
What does the s-block in the diagram represent?
The s-block represents the location of s electrons.
What does the d-block in the diagram represent?
The d-block represents the location of d electrons.
How many electrons does an atom of aluminum have?
A neutral atom of aluminum must have 13 electrons.
What is electron configuration?
Electron configuration is the representation of how the electrons in an atom are arranged.
Why is electron configuration important?
Electron configuration is important because it can be used to predict the properties of an element.
Which subatomic particle is the most important in chemistry?
The most important subatomic particle in chemistry is the electron.
How do electrons contribute to an atom's chemical properties?
An atom's chemical properties rely heavily on the arrangement of its electrons.
What are the properties of electrons?
Electrons are negatively charged, super speedy, very tiny, and elusive particles.
What can be determined by studying patterns of energy levels in elements?
Patterns of energy levels in elements can help identify the number of electrons in a neutral atom and how to write an electron configuration for neutral atoms.
How many total electrons does krypton have?
36
How many total electrons does chlorine have?
17
What does it mean when an atom has an electron configuration ending in p6?
It is very stable and won't react easily with other elements.
What does it mean when an atom has an electron configuration ending in s1 or p5?
It is very reactive.
What is the atomic number of an element?
The number of electrons in an atom's electron cloud.
Test your knowledge on electron configuration and learn how to predict the properties of elements based on the arrangement of electrons. Explore energy levels on the periodic table, identify the number of electrons in an atom, and practice writing electron configurations. Challenge yourself and master the world of subatomic particles.
