They can either gain, share, or lose electrons to have a full energy level
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
1, like all other alkali metal atoms.
A black crystal with atoms having 4 electrons in its outermost energy level could be carbon, which forms a structure like graphite or diamond. In these structures, each carbon atom has 4 valence electrons, enabling it to form strong covalent bonds with other carbon atoms.
Palladium, like other transition metals, has partially filled d orbitals in its outermost energy level. These d orbitals can hold a total of 10 electrons, but Palladium only has 9 electrons in its outermost energy level, leaving 1 electron shy of a complete d orbital set.
Atoms want to have a full outer energy level of electrons, typically either 2 or 8 electrons, to become stable. This is known as the octet rule, in which atoms tend to gain, lose, or share electrons to achieve a stable electron configuration like the noble gases.
When atoms form bonds and fill their outermost energy levels, they have an electronic arrangement similar to the nearest noble gas in the periodic table. This is known as the octet rule, where atoms strive to have a full valence shell like the noble gases for stability.
Energy transfer on the atomic level occurs through interactions such as collisions between atoms or through electromagnetic forces like radiation. When atoms collide, kinetic energy is transferred from one atom to another. Electromagnetic forces can transfer energy through the emission or absorption of photons by atoms.
All elements have energy levels, but they are never described as unfolded. The energy levels are like layers, similar to how a gobstopper has different layers of color. They cannot be unfolded.
Both hydrogen and cesium are considered s-block elements because the outermost electron in their atoms is located in an s orbital. In the periodic table, s-block elements are those where the outermost electrons are in the s orbital of their highest energy level.
The Bohr model describes atoms as having a nucleus surrounded by electrons in fixed energy levels. For neon, which has 10 electrons, the Bohr model would show two electrons in the first energy level, and eight electrons in the second energy level. The electrons in the outermost energy level determine neon's chemical properties.
There's only one. Because of this it is very easy for sodium to lose that one electron so that it can have a full electron shell like that of neon. Sodium's first shell has two electrons, and it's second shell has 8 electrons.
What it bonds with. If you have a noble gas (like Krypton), since its outer energy level is full, it won't bond with anything. But if you have Hydrogen, who has one electron in the outermost level, it can bond with any other element with enough space on it's outermost energy level.
