what elements on the periodic table have similar properties?
645
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals. Groups are numbered 1–18 from left to right.
428247
The key point is that, because all the elements in a given group have the same number of valence electrons, they form similar compounds. ... Copper is found in many ionic compounds in the form of either the Cu+ or the Cu2+ ion. The metallic elements are found on the left side and in the centre of the periodic table.

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.
1177299
Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons. ... For example, carbon with a mass number of 14 is called carbon-14. Atoms need a certain ratio of neutrons to protons to have a stable nucleus.
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.

Everything in the universe contains the atoms of at least one or more elements. The periodic table lists all the known elements, grouping together those with similar properties. Most elements are metals, which are shiny and conduct electricity well.
1018799
Reactivity of Alkaline Earth Metals All alkaline Earth metals have similar properties because they all have two valence electrons. They readily give up their two valence electrons to achieve a full outer energy level, which is the most stable arrangement of electrons.

For example, iodine and tellurium should be the other way around, based on atomic weights, but Mendeleev saw that iodine was very similar to the rest of the halogens (fluorine, chlorine, bromine), and tellurium similar to the group 6 elements (oxygen, sulphur, selenium), so he swapped them over.

Elements in the same group have the same number of valence electrons and so interact with other elements in a similar way. They display similar physical and chemical properties. For example, the halogens (F, Cl, Br, I) all react similarly.
434639
The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in their outer shell.

Some properties of an element can be observed only in a collection of atoms or molecules of the element. These properties include color, density, melting point, boiling point, and thermal and electrical conductivity.
1113323
Atoms of the same element that differ in their numbers of neutrons are called isotopes. Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and electrons.

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.

Nitrogen family elements display a wide range of physical and chemical properties. Their compounds may be transparent, either diamagnetic or paramagnetic at room temperature, and may conduct electricity when heated. Because the atoms form double or triple bonds, the compounds tend to be stable and potentially toxic.
