which elements on the periodic table have similar properties?
274419
Elements in the same group in the periodic table have similar chemical properties. This is because theiratoms 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.

The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure. ... All the discovered alkaline earth metals occur in nature, although radium occurs only through the decay chain of uranium and thorium and not as a primordial element.
1398694
Elements that are in the same period have chemical properties that are not all that similar. Consider the first two members of period 3: sodium (Na) and magnesium (Mg). In reactions, they both tend to lose electrons (after all, they are metals), but sodium loses one electron, while magnesium loses two.

Usually one or two isotopes of an element are the most stable and common. Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.
601179
The transition metals make up the middle block of the periodic table. Like the other elements that are grouped together (alkali metals, noble gases), these metals have very similar properties. Professor Stahl and his research group work with many of the transition metals.
1348023
The second column on the periodic table of the chemical elements is collectively called the alkaline earth metal group: beryllium, magnesium, calcium, strontium, barium, and radium. Because the outer electron structure in all of these elements is similar, they all have somewhat similar chemical and physical properties.
1238984
All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. ... Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.
255907
The periodic table is a tabular display of the chemical elements organized on the basis of their atomic numbers, electron configurations, and chemical properties. ... Elements with the same number of valence electrons are kept together in groups, such as the halogens and the noble gases.

Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.
1140104
The elements in a group have similarities in the electronic configuration of their atoms, and thus they exhibit somewhat related physical and chemical properties. The periodic table has eight main groups: 1, 2, 13, 14, 15, 16, 17, and 18 (previously numbered Ia, IIa, IIIa, IVa, Va, VIa, VIIa, and 0, respectively).

what do element in the same column in the periodic table have in common? the same number of valence electrons. what can you predict about an element from its position in the periodic table?
1012813
Group 2 elements share common characteristics. Each metal is naturally occurring and quite reactive. These metals are silver and soft, much like the alkali metals of Group 1. These metals also react with water, though not as vigorously.

Solution : (1) A pair of elements having similar properties due to similar atomic radii are called chemical twins and they are d-block elements of 5th and 6th period or 4d-series and 5d-series respectively. (2) They are Zr and Hf, Nb and Ta, Mo and W, Tc and Re.
816495
The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency. An example of a group in the periodic table is the alkali metal group.

Periodic Table of the Elements. The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.
757792
Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.
