Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more proton and electron and become less metallic.
Hope this helped you with your homework. :P
All the elements in the Periodic Table have the same general make up... that is, they are all made up of three things:protons, neutrons and electrons, although apart from that. Then they all simply differ in the ratio.
Hope that helps :)
Elements in the same period all have the same...number of valence electrons. Roughly speaking, it means atoms of that period have the same number of electrons available to interact with other atoms. This is more important for those elements filling their s and p orbitals which are drawn to the number of electrons of the nearest noble gas in the far right column, and then form ionic bonds (so H with 1 electron and Na with 11 electrons would each like to lose 1 electron <giving it a net positive charge> to get to the 2 electrons of He and 10 electrons of Ne respectively; while O with 8 electrons and S with 16 electrons would each gain 2 electrons <giving it a net negative charge> to get to the 10 electrons of Ne and 18 electrons of Ar respectively). In contrast, those elements in the middle of the table collectively called the transition elements, which are generally filling their f orbital, are not strongly drawn either direction and tend to form metallic bonds where all electrons are shared collectively.
The elements in a period have the same number of atomic orbitals.
Elements in same period have same shells. The number of shells for elements in same period are same. The elements are arranged in order of increasing atomic number.
The number of valence electrons
the same number of electron shells
Elements of same group have the same number of valence electrons and hence have similar properties.
Yes. Its true that elements with similar properties are found in same group.
Elements with same properties are present in same group. They are not present in same period. For example- alkali metals are present in same group.
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Elements in the same period have identical numbers of valence electrons or electrons in the outer energy level.
Elements of same group have the same number of valence electrons and hence have similar properties.
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Yes. Its true that elements with similar properties are found in same group.
Elements with same properties are found in same group.They are also called families.
Elements with same properties are present in same group. They are not present in same period. For example- alkali metals are present in same group.
Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
The Periodic table is a representation of all elements grouped in a manner that lists elements with similar properties in columns. Adjacent columns have deceasing or increasing characteristics
They have similar chemical properties.
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
Elements in the same period have identical numbers of valence electrons or electrons in the outer energy level.
Basically they are classified on the basis of repetition of similar properties......... Elements with same properties are assigned according to their groups.......each member of a particular group in a periodic table resembles almost similar properties elements with electron entering same shell is assigned same period....Thats how elements are classified
Elements in the same family-assuming family means classifications such as non-metals, metals-have similar properties.
