In very simple terms to achieve the octet atoms either lose valence electrons or gain them. The number of valence electrons for the period 2 elements is relativelly straightforward use the group number and remember to take 10 away from B, C, N, O and F. So as an example boron in group 13 has 3 valence electrons- so gain of +5 or loss of 3. Gaining five seems so excessive so your best guess is +3, which is true in say B2O3
As for using the periodic table to predict- not so easy- take gallium - in group 13 has 3 valence electrons- so it could lose 3 to give an octet, which indeed is its most common ON but can also lose 1 electron to form Ga+
What else can I help you with?
What is the element with the lowest oxidation state on the periodic table?
The element with the lowest oxidation state on the periodic table is Francium.
What is the trend of oxidation numbers in the periodic table?
Oxidation numbers generally become more positive from left to right across a period and more negative down a group on the periodic table. This trend is due to changes in the number of valence electrons as you move across and down the table, impacting how likely an atom is to gain or lose electrons.
How do oxidation numbers determine if an element is ametal or a nonmetal?
Oxidation numbers do not determine if an element is a metal or a nonmetal. The classification of an element as a metal or a nonmetal is based on its position in the periodic table and its physical and chemical properties. Metals are typically found on the left side of the periodic table, while nonmetals are found on the right side.
How can an elements Oxidation number be found?
The oxidation number of an element is typically determined based on its position on the periodic table and known oxidation rules. For example, in compounds, the sum of oxidation numbers must equal the overall charge. For atoms in their elemental form (such as O2 or Na), the oxidation number is zero.
Where is the oxidation number in the periodic table?
The oxidation number is not specifically listed on the periodic table. Oxidation numbers are assigned based on rules and guidelines that depend on the chemical properties and bonding of each element. Different elements can have multiple oxidation states, which can vary depending on the compound or molecule in which they are found.
What are the oxidation numbers for all the metals of the periodic table?
See link below.
What are the most common oxidation valence number in periodic table?
The most common oxidation states in the periodic table are +1, +2, +3, -1, -2, -3. These oxidation states are frequently observed in elements based on their position in the periodic table and their electron configuration.
What is the element with the lowest oxidation state on the periodic table?
The element with the lowest oxidation state on the periodic table is Francium.
