Helium had valence electron of 2 and filled the most inner ring so it is chemically robust and inert.
Outer valence electron ring contain 8 electrons so for Neon is robust as it had 2,8 electrons and Argon had 2,8,8 electrons and fill the outer ring.

Each hydrogen atom has 1 electron. When two hydrogen atoms combine they each share that electron with the other hydrogen atom, creating a covalent bond and a molecule of H2.
Not all ions are stable. Ions can be stable or unstable depending on their electron configuration. Some ions are stable because they have a full outer electron shell, while others are not stable and may react to achieve a more stable electron configuration. It's important to understand the concept of stability in relation to electronic configuration when considering ions.
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
Noble gases have a full outer electron shell, making them stable and unreactive. They do not easily gain or lose electrons since their electron configuration is already at its most stable state. This full outer shell configuration, known as the octet rule, makes noble gases chemically inert.

because of the electron configuration are different

Hydrogen forms an ionic bond with fluorine because fluorine is more electronegative than hydrogen, meaning it attracts electrons strongly and can easily accept an electron from hydrogen to form an ion pair. On the other hand, carbon and hydrogen have similar electronegativities, leading to the sharing of electrons in a covalent bond. This sharing allows both atoms to achieve a more stable electron configuration.
The octet rule states that atoms tend to gain, lose, or share electrons to achieve a stable electron configuration with 8 electrons in their outermost shell. Sodium has 1 electron in its outermost shell, so it tends to lose this electron to achieve a stable electron configuration, forming a sodium ion with a +1 charge.
Boron has the configuration with two filled shells and one outer electron. The outer electron has L=1, S=1/2, so J = 3/2 or 1/2. Hund's rules imply the term is the ground state term as in hydrogen.
In CH4, carbon forms four covalent bonds with four hydrogen atoms to achieve a stable electron configuration. Carbon contributes 4 valence electrons and each hydrogen contributes 1 valence electron, resulting in a total of 8 electrons around carbon, fulfilling the octet rule. This sharing of electrons between the atoms creates a stable molecule of methane.
the way you look that direction is correct..it is only one model to explain..
I'm unable to provide answers to specific questions about Gizmo activities. However, I can help explain electron configurations or provide assistance with understanding the concept. Let me know how I can assist you further.
An element's electron configuration determines its chemical properties, which in turn influence its placement on the periodic table. Elements with similar electron configurations tend to exhibit similar chemical behavior and are grouped together on the periodic table in columns (groups). The periodic table is organized based on similarities in electron configurations to help predict an element's properties based on its location.

In the context of the hydrogen atom, degeneracy refers to the phenomenon where different electron states have the same energy level. This is significant because it helps explain the spectral lines observed in the hydrogen spectrum, providing insights into the behavior of electrons in atoms.
