Elements that share properties of both metals and nonmetals are called A.

. They have the most in common between the two directions. -hydrogen has the same number of valence electrons as a Group 7A element -hydrogen like the alkali metals forms a cation with a 1 charge-hydrogen unlike the group 7A elements does not form covalent bonds-hydrogen has the same valence electron configuration as. Since elements in a group.

The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties. Electronic configuration of element X is 2 8 7. Hence the correct option is B Solve any question of Classification Of Elements And Periodicity In Properties with-.

Which of the following groups contains elements that are chemically similar to each other because. Elements with three electrons or. Elemental behavior is almost completely reliant on this outermost shell configuration with inner shells playing a less important role in determining properties.

The elements which are in the same groups have the same number of electrons in outermost orbit ie 1st group has 1 electron in outermost orbit 2nd has 2 electrons in outermost orbit 13th group has 3 14th has 4 and so on Also the periods of periodic table indicates the number of energy orbits or energy shells of an atom. See answer 1 Best Answer. Chemistry questions and answers.

Which is not a family of the periodic. They share the same number of electrons in. Elements in the same group have similar chemical properties.

Most of the time however we find chlorine as. Two elements within the same group. Elements within the same group in the periodic table have similar properties because they have the same number of A.

Solve any question of Classification Of Elements And Periodicity In Properties with-. Elements in the same group of the periodic table have similar properties because their electronic configurations have the same number of electrons in the outermost shell. Atomic number of K 19.

The elements in each group have the same number of electrons in the outer orbital. In the outer shell of all the elements in a group is the same as the group number. Occupy the same column on the periodic table and have the same number of electrons in thi outermost shell.

Elements from the same group have the same number of valence electrons but those electrons are at different energy levels from element to element. All the Group 1 elements - lithium Li sodium Na potassium K rubidium. The number of electrons.

Have the same number of electrons in their outermost shell. All the elements within the same group in the periodic table of elements have the same number of valence electrons. As you go down a group column the electrons may get further away from the positive charge of the nucleus be shielded by full lower levels of electrons or have energy overlap with d or f electrons.

Who are the experts. Number of valence electrons in X 7. The maximum oxidation number of say chlorine is VII the which it expresses in perchlorate ClO_4-.

The Group number represents the MAXIMUM oxidation state observed for the elementthe statement is neither true nor valid. Thanks for your question about elements in the same group on the periodic table. A period in the periodic table is a row of chemical elementsAll elements in a row have the same number of electron shells.

These are the electrons in the outer orbital. Take the halogens for exampleThese come from Group VII of the old Periodic Table. Have different numbers of electrons in their outemost shell.

Elements in the same group have the same number of Why are elements in the last group of the periodic table. This problem has been solved. Modern periodic table is compiled on the basis of atomic number of element.

Atomic number of element X 17. Good conductors of heat. Experts are tested by Chegg as specialists in their subject area.

All the elements in a group having the same number of valence electrons and hence have a similar outer electronic configuration. Occupy the same column on the periodic table of elements. Elements in the same group are those that are in a single vertical line from top to bottom.

Metals tend to be A. These valence electrons are those involved in bonding with other atoms to form compounds. Arranged this way groups of elements in the same column have similar chemical and physical properties reflecting the periodic law.

They are the electrons. Hence elements of each group or family have same number of electrons in their outermost or valence shell. All the elements in one group have the same number of valence electronsThe valence electrons are those on the energy level the most distant from the nucleus.

Those outer electrons are also called valence electrons. For example the group 1 or. Therefore valency of X 8-7 1.

Ii Elements 4 Be and 20 Ca both have two electrons each in their outermost shells. Main group elements in the same group have the same number of valence electrons.
