Where are the metallic elements found on the periodic table?
The alkaline-earth metals make up Group 2 of the periodic table, from beryllium (Be) through radium (Ra). Each of these elements has two electrons in its outermost energy level, which makes the alkaline earths reactive enough that they're rarely found ...
Where are the most dense metals on the periodic table?
The density of metals ranges from Osmium at the highest density to lithium at the lowest density of any metal.. Knowing the periodic table is key for most scientists. But just merely knowing the name of each and every one of the elements is not enough.
Where are most reactive metals on periodic table?
Salient Features
- The metals at the top of the reactivity series are powerful reducing agents since they are easily oxidized. ...
- The reducing ability of the metals grows weaker while traversing down the series.
- The electro positivity of the elements also reduces while moving down the reactivity series of metals.

What are the elements on the stair step line?
The elements on the stair step line are metalloids The elements to the right of the line are non metals. The elements to left of the line are metals . Metals have a relatively low electron negativity. The elements on the left of the periodic table are metals .
Is carbon a metal?
Carbon is a non metal but has some metallic properties. Silicon one row down in the same family is a true metalloid. While further down on periodic table lead in the same family is a metal. Answer link.
Where is hydrogen on the periodic table?
Exception: Hydrogen is a nonmetal which is located on the left top corner of the Periodic table.
How many nonmetals are there in the periodic table?
There are 18 nonmetals on the Periodic table. All these nonmetals are located on the upper right corner of the Periodic table (Hydrogen is located on the left top corner) In the above image, the nonmetals are represented in yellow color. [ Note: Astatine (atomic number 85) shows characteristics of nonmetals (halogens) as well as metalloids.
What is nonmetal in chemistry?
Or in other words nonmetals are those elements which do not possess the properties of metals. Well, now let me tell you the proper definition of nonmetals used in chemistry.
Which nonmetals are the most reactive?
Actually the halogens are the most reactive nonmetals, but we know that as we move down the group, the electronegativity decreases. In other words, Fluorine is at the top of the halogen group and it has less atomic size plus it needs only one electron to complete the octet.
Which element has the highest electronegativity?
Also the atomic size of fluorine is very small. (Check this Periodic table guide, for atomic size trend) And because of its smaller size and need of only one electron, it has the highest electronegativity. Electronegativity is nothing but a tendency to attract the electron pair towards it.
Is bromine a nonmetal?
Nonmetals are found in solid state, liquid state as well as gaseous state. 11 non metals are in gaseous state at room temperature. Bromine (Br) is a nonmetal which is in liquid state at room temperature. Rest of the nonmetals are solids at room temperature.
