Elements in the same group (in theperiodic table) have similar chemical properties.This is because their atoms have the same number ofelectrons in the highest occupied energy level. Group 1elements are reactive metals called the alkali metals.Group 0 elements are unreactive non-metals called thenoble gases..
Also, why do all the elements of the same group have similar properties?
a) Elements in the same group have similarproperties because they have the same number ofvalence electrons in their outermost shell. b) Elements inthe same period have different properties because thenumber of valence electrons in their outermost shellsdiffer.
Beside above, what do elements in the same group have in common? Elements in the same group are those that are ina single vertical line from top to bottom. They have themost in common between the two directions. They share thesame number of electrons in their valence subshells. As aresult, they will all have the same chemicalreactivity.
Also asked, what causes the similar chemical characteristics of elements that belong to the same group?
Thus, all the elements in a group havesimilar valence shell electronic configuration. Thesimilar chemical nature of elements in a group is dueto similar electron structures of their atoms.
How can you determine if elements have the same chemical properties?
Core electrons are also referred as non-valenceelectrons. Two different elements have similar chemicalproperties when they have the same number of valenceelectrons in their outermost energy level. Elements in thesame column of the Periodic Table have similarchemical properties.

What determines an atom's reactivity?
The number of electrons in the outermost shell of anatom determines its reactivity. Noble gases have lowreactivity because they have full electron shells. Halogensare highly reactive because they readily gain an electron tofill their outermost shell.What kind of elements tend to gain electrons?
Elements that are metals tend to loseelectrons and become positively charged ions called cations.Elements that are nonmetals tend to gain electronsand become negatively charged ions called anions. Metals that arelocated in column 1A of the periodic table form ions bylosing one electron.Why is argon unreactive?
Argon is unreactive because it has themaximum number of electrons in its outer shell.Do elements in the same period have similar physical properties?
A period in the periodic table is a rowof chemical elements. All elements in a rowhave the same number of electron shells.Arranged this way, groups of elements in the same column havesimilar chemical and physical properties, reflecting theperiodic law.What are the three major categories of the elements?
Of the three major categories of elements(metals, non-metals, and metalloids) which group is the largest?They are malleable, ductile, shiny, good conductors of electricityand thermal energy.How are elements in the same group similar?
For example elements in the alkali metalgroup have one extra electron in their outermost shell.Electrons determine the chemical reactivity of an element,so the elements in the same group have the samenumber of electrons on the outer post shell, giving themsimilar chemical properties.Are oxygen and selenium in the same period or group?

The alkali metals, found in group 1 of theperiodic table (formerly known as group IA), are veryreactive metals that do not occur freely in nature. Thesemetals have only one electron in their outer shell.What elements have similar properties?
Only choice C refers to elements in the samegroup. Lithium (Li), sodium (Na) and potassium (K) are part ofgroup I of the periodic table and are known as alkali metals andhave similar properties.Why are Group 7 elements called halogens?
The term "halogen" means "salt-former" andcompounds containing halogens are called "salts". Allhalogens have 7 electrons in their outer shells,giving them an oxidation number of -1. The halogens exist,at room temperature, in all three states of matter: Solid- Iodine,Astatine.Why do elements in the same family have similar physical and chemical properties?
The elements in the same group has similarnumber of valence electrons. They have identical number ofelectrons in their outermost shell. e.g. All the alkali metals inGroup 1 have 1 valence electron, so they all tend to reactthe same way with other substances.How many gaseous elements are there?

Which elements are in the same period?
The periods are numbered 1 through 7 on theleft-hand side of the table. Elements that are in thesame period have chemical properties that are not all thatsimilar. Consider the first two members of period 3:sodium (Na) and magnesium (Mg).What is Group 14 on the periodic table called?
The carbon group is a periodic table groupconsisting of carbon (C), silicon (Si), germanium (Ge), tin (Sn),lead (Pb), and flerovium (Fl). In modern IUPAC notation, it iscalled Group 14.Why do elements in same group have same physical and chemical properties?
Elements in the same group (in theperiodic table) have similar chemical properties. This isbecause their atoms have the same number of electronsin the highest occupied energy level. Group 1elements are reactive metals called the alkali metals.Group 0 elements are unreactive non-metals called thenoble gases.Do elements in the same group have the same physical properties?
Elements in the same group of the periodic tableshow trends in physical properties, such as boiling point.They have the same number of electrons in their outer shell,so they are similar in their chemicalproperties.Is an element that is soft and easy to cut?

Mercury is nearly twice as heavy astin. Explanation: The density of mercury is 13.534g/cm3, and the density of tin is 7.31 g/cm3. This means thatone cubic centimeter of mercury has a mass of 13.534 g, andone cubic centimeter of tin has a mass of 7.31g.
