Which elements have similar chemical properties in sulphur and helium?
Sulphur and helium have entirely different properties. Sulphur has properties similar to group 16 elements. Helium has properties similar to group 18 elements.
Why is helium normally placed in group 18?
We all know that helium is a noble gas. It has atomic number 2 but it is placed in 18 group be because in 1st group the elements have only one electron in thier s orbital e.g. Hydrogen, lithium, sodium, potassium etc. But helium has two electron so it cannot exist in 1 group. In second group the s orbital are same but the physical and properties of helium is different from the elements present in second group. According to modern periodic table elements which have same physical properties are placed in same group. Since helium is an inert gas and its physical properties are similar to the other elements of the 18 group and also helium discoverd late so that hilium can be put in the 18 group
How many families are in the periodic tables?
There are 18 families. They are made according to the properties of elements. So the elements in a group has similar properties.
Why do the elements in the vertical columns all have the same chemical properties?
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
How do you find the most similar elements in the periodic table?
In the periodic table, the elements are grouped according to their properties. Elements in a group has an equal number of valence electrons. So the elements in a group have most common chemical properties.

What elements have the same properties as argon?
Argon is a nobel gas. Nobel gases are located in Group 18. Elements have similar properties within the same group. Argon has similar properties to Helium, Neon, Krypton, Xenon, and Radon.

Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.

What are the physical properties of the element argon?
Argon has atomic number 18 and is the third element in group 18 of the periodic table
What is a column of elements in a periodic table?
The columns are called groups. They are also called families. There are 18 groups in Periodic Table.A column is known as a group in periodic table. There are 18 groups in the modern setting of periodic table. Elements in the same group usually share same chemical properties and striking physical characteristic trends.
Using a periodic table how would you find elements with chemical properties similar to helium?
Elements in the same group or column on the periodic table have similar chemical properties. Helium is in group 18 or the Nobel gases. Elements with similar chemical properties would be the rest of the elements below Helium Neon, Argon, Krypton, Xenon, and Radon
