What is an atom's electron configuration?
The arrangement of electrons in an atom.
What three methods are use to represent the arrangement of electrons?
Electron configuration: Represents the distribution of electrons in an atom's energy levels or orbitals. Lewis structure: Shows the arrangement of valence electrons in a molecule or ion, typically using dots to symbolize electrons. Orbital diagram: Illustrates the distribution of electrons in an atom's orbitals, depicting each orbital as a box and arrows to represent electrons with their spin.
Which formula shows the numbers and types of atoms in a molecule but not the bond?
The molecular formula shows the numbers and types of atoms in a molecule but does not show the bonding arrangement between the atoms. It gives the simplest whole-number ratio of the different types of atoms in a compound.
What represents a compound which is an arrangement of all symbols and numbers?
A chemical formula is a representation of a compound using symbols of elements and numbers indicating the ratio of atoms. It shows the types and numbers of atoms present in a compound.
Niels Bohrs' theory of the atom shows electrons moving around the nucleus in specific paths called?
Niels Bohr's theory of the atom proposed that electrons move around the nucleus in specific, fixed paths called orbits or energy levels. These orbits have specific energy levels and are sometimes referred to as shells.
What is an atom's electron configuration?
The arrangement of electrons in an atom.
What does the configuration of an atom shows?
The configuration of an atom shows the arrangement of electrons in its energy levels or orbitals. This configuration determines the atom's chemical properties and how it will interact with other atoms to form compounds.
What is 1s2 2s2 2p6 3s2?
That electron configuration represents the electron arrangement of a neutral atom of magnesium (Mg), which has 12 electrons. It shows the distribution of electrons in various energy levels or shells: 1s2, 2s2, 2p6, and 3s2.
What is a chemical formula that shows the numbers and kinds of atoms in a molecule but is not the arrangement of the atoms?
A chemical formula provides information about the types and numbers of atoms in a molecule, but it does not reveal the spatial arrangement of those atoms in the molecule. It is a concise way to represent the composition of a substance using chemical symbols and numerical subscripts.

How many valence electrons are in Cl atom?
There are 7 valence electrons in a chlorine atom. The atomic number of chlorine is 17, which means it has an electron configuration of 2,8,7. This shows it has 3 shells of electrons, with 7 in the outer level.
Which electrons do a Lewis structure show?
A Lewis structure shows the valence electrons of an atom, which are the electrons in the outermost energy level. These electrons are involved in chemical bonding and determine the atom's reactivity and bonding behavior.
How many core shells does calcium have?
Calcium is in group 2, period 4 of the periodic table. It has an electron configuration of 1s2 2s2 2p6 3s2 3p6 3d10 4s2. This shows us that 4 is its valence shell. Therefore, the other 3 shells are its core shells.
What is the orbital diagram for vanadium?
The orbital diagram for vanadium shows five electrons in the 3d orbital and two electrons in the 4s orbital. This arrangement reflects the electron configuration of vanadium, which is Ar 3d3 4s2.
What is the orbital diagram for the element carbon?
The orbital diagram for the element carbon shows two electrons in the 1s orbital, two electrons in the 2s orbital, and two electrons in the 2p orbital. This arrangement follows the Aufbau principle and Hund's rule.
Which formula shows the numbers and types of atoms in a molecule but not the bond?
