How to Use valence electron configuration to explain why helium is safer than hydrogen for use in airships?

∙ 14y ago
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.

Are some discrepancies in the electron configuration of some elements?

Explain what happens when two hydrogen atoms bond?
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.
Explain what atoms are trying to achieve in there electron shells when they bond with each outher?
Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
How did Bohr explain the line spectrum of hydrogen?
The difference in energy between the energy levels determines color of light emitted when an electron moves from one energy level to another.
Explain what a noble-gas electron configuration is?
The noble gas notation is a notation formed as a result of the electron configuration notation being used in conjunction with noble gases. The noble gas preceding the element in question is written then the electron configuration is continued from that point onwards. The notation is shorter to write and makes it easier to identify elements. The noble gas notation starts for elements after helium. For example, the electronic configuration of carbon is 1s2 2s2 2p2, whereas its noble gas notation is [He] 2s2 2p2.

Explain why the table of elements is periodic?
because of the electron configuration are different

Explain why there should be a connection between an element electron configuration and its location on the periodic table?
An element's electron configuration determines its location (group) in the periodic table. It tells us how many valence electrons (s and p sublevel).
How does the octet rule explain the formation of a sodium ion?
Na atom ion has an electronic configuration 2,8,1 On losing one electron it forms Na+ cation, with the configuration of 2,8 thereby obeying octet rule.
What is the significance of the line spectrum of hydrogen?
the line spectrum of the hydrogen spectrum indicates that only certain energies are allowed for the electron of the hydrogen atom. In other words, the energy of the electron in the hydrogen atom is quantized.
In which direction the electron revolve around the nucleus of hydrogen atom?
the way you look that direction is correct..it is only one model to explain..

Did Bohr's model of the atom explain hydrogen's flammability?
Bohr's model of the atom doesn't explain hydrogen's flammability.
How do you explain the diagram that shows 4 energy levels of hydrogen - 1 at the bottom 4 at the top - the values are n4-0.85eV n3-1.51eV n2-3.4eV n1-13.6eV?
The diagram shows the ionization energies of hydrogen. The ionization energy for a ground-state electron in hydrogen is 13.6eV. Let's jump. An electron orbits an atom of hydrogen in as low an energy level as possible. That's the ground state of hydrogen. To tear that electron away, it takes some amount of energy. In this case, it takes 13.6eV to strip off that electron. But what if the electron is in the next higher allowable energy level because the gas it hot? In that case, it takes less energy to tear that electron away because you've got a "head start" owing to the fact that the electron is in a higher orbital than the ground state. And what if it's in the next higher allowable energy level? Or the next? Less and less energy is required to strip off the electron as it moves to higher energy levels. These are the ionization energies of hydrogen. These energy levels are specific to hydrogen. Each other element will have a different set if ionization energies associated with it. And with atoms with many electrons and complex electron structures, the problem can quickly become very complex.
