The elements in a particular group behave the same because they all react to achieve stability the same way. i.e. gain a full outer shell. The elements in group 8 are generally non-reactive because they are stable. elements in groups 1 and 7 for instance will react well with each other because group 1 elements willingly give up their extra electron and elements from group 7 need that extra electron to become stable. All of the group 7 elements are trying to gain an electron so they all behave the same way, in regards to reactivity.
group 1- tends to lose 1 electron to form stability- reacts well with group 7
group 2- tends to lose 2 electrons to form stability- reacts well with group 6
group 3- tends to lose 3 electrons to form stability- reacts well with group 5
group 4- tends to gain or lose 4 electrons, depending- reacts well with other elements from group 4
group 5- tends to gain 3 electrons to form stability- reacts well with group 3
group 6- tends to gain 2 electrons to form stability- reacts well with group 2
group 7- tends to gain 1 electron to form stability- reacts well with group 1
group 8- already stable- generally non-reactive.
p.s. when I say reacts WELL, I mean the two elements then achieve stability and are considered 'happy'
Does that make any sense?
What else can I help you with?
What are the non toxic elements?
Some examples of non-toxic elements include helium, neon, argon, and krypton. These elements are considered non-toxic because they do not react with the human body in harmful ways and are generally safe to be around in normal conditions.
Valence lithium sodium do they react in similar ways?
They both have a valency of 1 as their atoms all have 1 electron in the outermost orbits. (lithiium's electronic structure is 2,1, sodium 2,8,1) Because of this Lithium and sodium react very similarly. They both react quickly in air (and therefore have to be stored in oil to protect them). They both react vigorously with water producing hydrogen and forming an alkaline solution. They both burn with coloured flames - lithium red and sodium yellow. Thee are several other metals all belonging to the same 'family' - the group 1 elements or 'alkali metals'. Others include Potassium, Rubidium and Caesium.
What are all the periodic table families called?
A family is a vertical column in the periodic table. Elements in a family all share similar characteristics, whether they be physical or chemical. There are 18 family (or group) columns in the periodic table.
Which best describes john Dalton's observations of elements in any given compound?
Dalton discovered that the atoms that combine to form compounds are distinguished from one another by their atomic weights. He also learned that all atoms of a given element are identical.
Do valence electrons affect the reactivity of an element?
atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy. It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.
Elements in the same group or family of the periodic table are similar in what way?
Elements in the same group or family of the periodic table have the same number of valence electrons, which gives them similar chemical properties. This similarity in valence electron configuration allows them to react in similar ways with other elements.
What do elements in the same group in the periodic table have in common?
They have the same number of valence electrons, or electrons in the outer electron shell. This allows them to react with certain elements.
How can you tell the elements have similar properties by using a periodic table?
Elements with similar properties are found in the same group or column on the periodic table. This is because they have the same number of valence electrons, which influences their chemical behavior. Elements in the same group tend to react in similar ways and have comparable physical properties.
Atoms of elements in a group on the periodic table have similar chemical properties this similarity is most closely related to the atoms?
having the same number of electrons in their outermost electron shell. This is known as the valence electrons, which dictate the elements' reactivity and chemical behavior. Elements in the same group tend to react in similar ways because they have the same number of valence electrons.
Why do elements in a group all behave similarly?
Elements in the same group behave similarly because they all have the same number of electrons in their outer-most orbits. These electrons are what determines the types of bonds and chemical reactions the atom can undergo.
What are the vertical columns on the periodic table calles?
The vertical columns on the periodic table are called groups. The table is arranged in such a way that all elements in the same group are similar and have the same number of valence electrons.
What element is most like chlorine?
Bromine is the element most like chlorine because they belong to the same group in the periodic table. They have similar chemical properties and react in similar ways with other elements.
Do elements in the periodic table have similar qualities?
Elements in the periodic table with similar qualities are grouped together in columns called groups or families. Elements within the same group share similar chemical properties because they have the same number of valence electrons. This allows them to react in similar ways with other elements.
Why do atoms with the same number of valence of electrons have similar chemical properties?
Because atoms with the same number of valence electrons react in similar ways with other elements.
Why do elements in the same column have similar properties?
Elements in the same column, called a group, have similar properties because they have the same number of valence electrons. Valence electrons determine an element's reactivity and chemical behavior, so elements in the same group tend to react in similar ways.
Why elements share similar characteristics?
Elements share similar characteristics because they have the same number of electrons in their outermost energy level, which determines their chemical properties. This similarity is due to their placement in the periodic table, where elements in the same group have the same number of valence electrons. These shared characteristics allow elements to react in similar ways and form similar types of compounds.
How are elements put into columns with other elements?
Elements in the same column on the periodic table share similar chemical properties because they have the same number of valence electrons. This allows them to form similar types of bonds and react in similar ways with other elements. The columns, or groups, are arranged based on the number of valence electrons in each element.
