Sc i believe is the one u trying to answer.. woop a 2nd chem question.. lucky i take chem haha :P
A Lewis electron dot diagram for a group 13 element, such as aluminum, represents the valence electrons surrounding the element's symbol. Group 13 elements have three valence electrons, so the diagram would show the element's symbol (e.g., Al) with three dots placed around it to indicate the three valence electrons. These dots can be arranged in various configurations, typically with one dot on three sides of the symbol. This visual representation helps in understanding bonding and reactivity of the element in chemical reactions.
This is the Lewis dot notation.
To determine which diagram in Figure 8.14 shows an element with three valence electrons, look for a representation of an element in Group 13 of the periodic table, such as aluminum (Al). Elements in this group typically have three valence electrons, indicated by three dots or lines around the element symbol in the diagram. If you can identify the diagram that corresponds to this configuration, that will be the correct one.
The symbol for an element that does not need eight electrons to have a full set of valence electrons is typically found in Group 1 or Group 2 of the periodic table. Examples include lithium (Li) from Group 1 and beryllium (Be) from Group 2. These elements follow the duet rule or satisfy the octet rule in a different way.
Tellurium element has 52 electrons.It has symbol Te.
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
Yes, that is correct. The number of dots around an element's symbol in the periodic table corresponds to the number of valence electrons that element has. Valence electrons are the outermost electrons in an atom and play a significant role in determining an element's chemical properties.
The system used to represent the valence electrons around the chemical symbol of an element is called the Lewis electron dot structure or simply Lewis structure. In this system, dots are placed around the chemical symbol to represent the valence electrons of the element.
Calcium has 2 valence electrons and 4 electron shells. It is represented by the chemical symbol Ca.
Pb with 4 dots around it to represent its 4 valence electrons.
A Lewis electron dot diagram for a group 13 element, such as aluminum, represents the valence electrons surrounding the element's symbol. Group 13 elements have three valence electrons, so the diagram would show the element's symbol (e.g., Al) with three dots placed around it to indicate the three valence electrons. These dots can be arranged in various configurations, typically with one dot on three sides of the symbol. This visual representation helps in understanding bonding and reactivity of the element in chemical reactions.
To draw Lewis dot structures for elements, determine the total number of valence electrons for the element. Then, place the electrons around the element symbol in pairs, following the octet rule (except for hydrogen and helium, which follow the duet rule). Remember to show all valence electrons and distribute them evenly around the element symbol.
This is the Lewis dot notation.
Oxygen has 6 valence electrons. The dot diagram for oxygen would show 6 dots around the symbol "O", with pairs of dots on each side of the element symbol.

The element is aluminum (atomic number 13). In its electron-dot structure, aluminum will show three valence electrons arranged around the element's chemical symbol.

Examples include lithium (Li) from Group 1 and beryllium (Be) from Group 2. These elements follow the duet rule or satisfy the octet rule in a different way.
