Why do different groups of the periodic table want to gain or lose different numbers of electrons?
Because they are all trying to be like noble gases. Noble gases are like the templates that all other elements what to be like because they are stable. They lose different numbers because they all have different amounts of electrons to begin, so it would make since that they would have to lose different amounts of electrons to get to 8 (the amount of electrons a noble gas has). Hope that helps

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.
What are the different rows of elements in the periodic table called?
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
What do the groups in the periodic table mean?
The group number, in addition to designating the group of a column, also gives the number of valence electrons in an atom in that group. For example, with a group number of one, lithium, sodium, potassium, and the other alkalis all have one valance electron. Note that some periodic tables use a different format, and the number of valence electrons in groups after the transition metals is the group number minus 10.
What are groups in the periodic table?
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
What is the relationship between the periodic table periods and groups in terms of organizing elements based on their properties?
Periods in the periodic table refer to the horizontal rows, while groups refer to the vertical columns. Elements in the same group have similar properties because they have the same number of valence electrons. Elements in the same period have different properties because they have different numbers of electron shells. The periodic table organizes elements based on their properties, with elements in the same group sharing similar characteristics.
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.
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
What makes inert gases different from the other groups in the periodic table?
Inert gases, also known as noble gases, have full valence shells of electrons, making them stable and unreactive. This stability is due to their complete octet of electrons. In contrast, other groups in the periodic table have varying numbers of valence electrons and are more likely to form chemical bonds with other elements to achieve stability.
What does a group indicate?
The columns of the periodic table are called groups.
What does groups in a periodic table have?
atoms in a group have the same number of valence electrons
Why does helium and hydrogen does not come in agroup of periodic table?
Helium has 2 valence electrons and hydrogen has 1 electron. So, they are placed in different groups.
What are the different rows of elements in the periodic table called?
The rows of elements in the periodic table are called periods. There are a total of 7 periods in the periodic table, each representing a different energy level or shell in which the elements' electrons are arranged.
What on periodic table groups have in common?
The groups have equal number of valence electrons. The elements in same groups have same chemical properties.
What are the 2 groups that divide the periodic table and their properties?
Metals and non-metals are the two groups. Metal loose electrons. Non metals gain electrons.
What do the groups in the periodic table mean?
The group number, in addition to designating the group of a column, also gives the number of valence electrons in an atom in that group. For example, with a group number of one, lithium, sodium, potassium, and the other alkalis all have one valance electron. Note that some periodic tables use a different format, and the number of valence electrons in groups after the transition metals is the group number minus 10.
How groups are there in the modern periodic table?
The group number tells you the number of valence electrons in the outer shell. This is important because it is the valence electrons that participate in bonding, and thus in determining the properties of the element.
What are groups in the periodic table?
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
