All the elements in one group have the same number of valence electrons. Since elements in a group have the same number of valence electrons, they behave similarly in chemistry. An example would be the alkali metals (excepting hydrogen. Hydrogen is in this group only because it has one valence electron..
Keeping this in view, how are elements in the same group similar?
1 Answer. The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.
what causes the similar chemical characteristics of elements that belong to the same group? Elements in the same group (in the periodic table) have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level. Group 1 elements are reactive metals called the alkali metals. Group 0 elements are unreactive non-metals called the noble gases.
Also to know is, what 3 things elements in the same group have in common?
Elements in the same group are those that are in a single vertical line from top to bottom. They have the most in common between the two directions. They share the same number of electrons in their valence subshells. As a result, they will all have the same chemical reactivity.
Are elements in the same period similar?
All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor. Arranged this way, groups of elements in the same column have similar chemical and physical properties, reflecting the periodic law.

What elements are in the same group?
The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements. Every element in the first column (group one) has one electron in its outer shell.How many gaseous elements are there?
11
How do you find the group and period of an element?
The period of an element corresponds to the principal quantum number of the Valence shell. The block of an element corresponds to the type of orbital which receive the last electron. For s-block elements , group number is equal to the number of valence electrons.Which groups are the most reactive?
The two most reactive groups of elements are the alkali metals and the halogens, because of their valence electrons. Those groups have 1 and 7 valence electrons, respectively, making them desperate to bond to something, to achieve a stable configuration of 8.What determines an atom's reactivity?
The number of electrons in the outermost shell of an atom determines its reactivity. Noble gases have low reactivity because they have full electron shells. Halogens are highly reactive because they readily gain an electron to fill their outermost shell.Why are Group 7 elements called halogens?
Group 7 – The Halogens. The elements in Group 7 of the Periodic Table are all non-metals. They have been given the name halogens from the Greek words meaning 'salt makers'. The salt in your kitchen, sodium chloride, is a compound of the halogen chlorine.Why do elements in a group show same Valency?
Elements in same group show same valency because they have same number of electrons in ther outermost shell i.e. Valence shell. Since valency depends upon the valence electrons so they have same valency. Elements in the same group have same valancy. These elements also have similar physical and chemical properties.What is Group 14 on the periodic table called?
The carbon group is a periodic table group consisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn), lead (Pb), and flerovium (Fl). In modern IUPAC notation, it is called Group 14. In the field of semiconductor physics, it is still universally called Group IV.What do elements have in common?
The common feature is that the atoms of all elements consist of electrons, protons, and neutrons.What do elements in a family have in common?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.What is the number of valence electrons in phosphorus?
five
How many groups are in the periodic table?

What is Group 5 called on the periodic table?
Group 5 (by IUPAC style) is a group of elements in the periodic table. Group 5 contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.What do elements in group 6 have in common?
Group 6 element. Group 6, numbered by IUPAC style, is a group of elements in the periodic table. Its members are chromium (Cr), molybdenum (Mo), tungsten (W), and seaborgium (Sg). These are all transition metals and chromium, molybdenum and tungsten are refractory metals.What group of elements are the most reactive nonmetals?
Answer and Explanation: The most reactive nonmetal is fluorine. Fluorine is a halogen, which is Group 17 on the periodic table, and the halogens are the most reactiveWhy do we classify elements?
The number of elements discovered has increased, making it difficult to remember the behavior and properties of these elements. Hence it is important to classify elements according to their properties. It helps us understand how different elements form different compounds.How many naturally occurring elements are there?

1 Answer. The elements in the same group has similar number of valence electrons. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.What are the 7 families of the periodic table?
This list includes alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides, as well as seven elements in groups 3 through 6—aluminum, gallium, indium, thallium, tin, lead, and bismuth.
