Atomic Structure
This subatomic particle has a positive charge and is found in the nucleus of an atom.
What is a proton?
This letter represents the first energy sublevel.
What is "s"?
This trend increases as you move across a period from left to right and decreases as you move down a group.
What is electronegativity?
This experiment, led by Ernest Rutherford, led to the discovery that atoms have a small, dense, positively charged nucleus.
What is the Gold Foil Experiment?
The atomic number for Zr?
What is 40?
Atoms of the same element with different numbers of neutrons are called this.
What are isotopes?
This is the maximum number of electrons that can be held in the first energy level.
What is 2?
This property of elements increases as you move down a group due to the addition of electron shells.
What is atomic radius?
This scientist introduced the model of the atom with electrons orbiting the nucleus in specific energy levels.
Who is Niels Bohr?
This element, with the atomic number 6, is essential for all living organisms and is found in organic compounds.
What is carbon?
This term describes the average mass of an element’s isotopes, weighted by their natural abundance.
What is atomic mass?
The number of electrons a single p orbital can hold.
What is 2?
Elements in this group are known for being highly reactive and have a single electron in their outer shell.
What are alkali metals?
Bohr's model improved upon this earlier atomic model that couldn’t explain atomic spectra.
What is the Rutherford model?
This subatomic particle is found in the nucleus of an atom and has no electric charge.
What is a neutron?
This notation describes the distribution of electrons in an atom's orbitals, typically represented in terms of subshells like s, p, d, and f.
What is electron configuration?
The electron configuration for oxygen ends with this.
What is 2p⁴?
This term describes elements found in the center of the periodic table, known for conducting electricity and being malleable.
What are transition metals?
In Bohr's model, electrons travel around the nucleus in these fixed, circular paths
What are energy levels or orbits?
This type of bond is formed when electrons are shared between atoms, often seen in molecules like water.
What is a covalent bond?
The smallest unit of an element that retains its properties is called this.
What is an atom?
The element with the electron configuration 1s² 2s² 2p⁶.
What is Neon (Ne)?
This energy increases across a period but decreases down a group, making it harder to remove an electron from the outer shell.
What is ionization energy?
The energy of an electron in Bohr’s model depends on this, which is quantized in discrete steps.
What is the electron’s distance from the nucleus (or the principal quantum number)?
Who is the best science teacher?
Ms. Lewis
