Which group has different numbers of valence electrons?
Noble gases have a full valence shell with 8 electrons, while all other groups typically have fewer valence electrons. Transition metals have varying numbers of valence electrons depending on their position in the periodic table.
Do metals have both positive and negative oxidation numbers?
No, the can only have positive oxidation numbers
The force of attraction by group 1 metals for their valence electrons is?
The force of attraction by group 1 metals for their valence electrons is weak. This is because group 1 metals have a single valence electron that is loosely held and easily lost to form positive ions.
Can metals have positive and negative oxidation numbers?
Yes, metals can have positive oxidation numbers when they lose electrons to form cations. However, metals typically do not have negative oxidation numbers since they usually do not gain electrons to form anions.
How many valence electrons may metals have?
Different metals have different numbers of valence electrons. The alkali metals have 1. The alkaline-earth, transition, and inner transition metals have 2. Aluminum and those in its column have 3, tin and lead have 4.
What is used to name metal elements with variable numbers of valence electrons?
The transition metals.
Does a metal or nonmetal have both positive and negative oxidation numbers?
A metal typically has only positive oxidation numbers, while a nonmetal can have both positive and negative oxidation numbers. Metals tend to lose electrons (positive oxidation numbers) to form cations, while nonmetals can gain or lose electrons to form a variety of oxidation states.
Do metals contain fewer valence electrons?
No, metals typically have fewer valence electrons compared to nonmetals. Valence electrons are the outermost electrons in an atom, involved in bonding and determining the reactivity of an element. Metals tend to have fewer valence electrons which allows them to easily lose electrons and form positive ions.
What charges do the metals achieve after they form ions?
The charge on the metals depends on their configuration.Metal with one valence electron donate it and acquire one positive charge.
How many valence electrons does a group 1 metal have?
Group 1 metals, also known as alkali metals, have one valence electron. This single valence electron is responsible for their high reactivity and tendency to form positive ions by losing that electron. Examples of group 1 metals include lithium, sodium, and potassium.
How many valence electrons are in alkali metals?
one valence electrons
Are electron affinity values usually positive or negative numbers?
Positive for nonmetals and negative for metals
