except that there are also two dots both above and below the "Br" in the diagram (there are three lone pairs on Br, and none on K)

Lithium: Li has 1 valence electron, so its Lewis dot diagram is Li: . Bromine: Br has 7 valence electrons, so its Lewis dot diagram is :Br:. Carbon: C has 4 valence electrons, so its Lewis dot diagram is :C:. Hydrogen: H has 1 valence electron, so its Lewis dot diagram is H: . Silver: Ag has 1 valence electron, so its Lewis dot diagram is Ag: . Oxygen: O has 6 valence electrons, so its Lewis dot diagram is :O:. Iron: Fe has 2 valence electrons, so its Lewis dot diagram is :Fe:. Potassium: K has 1 valence electron, so its Lewis dot diagram is K: . Oxygine: I'm not familiar with an element called "oxygine". It may be a misspelling of oxygen. If so, refer to oxygen's Lewis dot diagram above.
The rings around the potassium (K) diagram represent the energy levels or electron shells where electrons are likely to be found. They are organized into different levels, with each level holding a specific number of electrons. The outermost ring is the valence shell, which determines the chemical properties of the element.
Bromine is paramagnetic. This is because the 4p subshell has a value of 4p5. 5 electrons in a p subshell (which has space for 6), means the last electron is unpaired. The unpaired electron gives it the property of paramagnetism. Alternatively, Selenium is diamagnetic, as it has the outer subshell 4p4, meaning no electrons are unpaired.

In the electron dot diagram for calcium, there are two dots shown, as calcium has two valence electrons.
The Lewis Dot Diagram of KBr would show potassium (K) with one valence electron and bromine (Br) with seven valence electrons. The potassium atom would donate its electron to the bromine atom to form an ionic bond, resulting in a stable octet for each atom.

In the reaction between potassium and fluorine, potassium atoms will lose one electron each to form potassium ions, while fluorine atoms will gain one electron each to form fluoride ions. The potassium ions and fluoride ions will then combine to form potassium fluoride salt.
Potassium would be more reactive because it has one valence electron, making it easier to lose that electron and form a positive ion compared to silicon, which has four valence electrons. Silicon is less likely to gain or lose electrons due to its stable electron configuration.
In potassium fluoride (KF), potassium loses one electron to achieve a stable electron configuration, forming a K+ cation, while fluorine gains one electron to achieve a stable electron configuration, forming a F- anion. The attraction between the positively charged potassium ion and the negatively charged fluoride ion leads to the formation of an ionic bond in KF.
Bromine is paramagnetic. This is because the 4p subshell has a value of 4p5. 5 electrons in a p subshell (which has space for 6), means the last electron is unpaired. The unpaired electron gives it the property of paramagnetism. Alternatively, Selenium is diamagnetic, as it has the outer subshell 4p4, meaning no electrons are unpaired.
Yes, each dot in an electron dot diagram represents a valence electron. Valence electrons are the electrons in the outermost energy level of an atom, and they are the ones involved in forming chemical bonds with other atoms.
A dot diagram, or Lewis dot structure, illustrates the valence electrons of an atom. Calcium (Ca) has two valence electrons, represented by two dots, while potassium (K) has one valence electron, represented by a single dot. Therefore, the dot diagram for calcium would show two dots around the symbol, while potassium would show one dot.
