What sets of elements have similar physical and chemical properties?
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
Elements in a have similar chemical properties?
a group of elements that have similar properties are arranged one on top of the other on the periodic table. These groups are also called families
Which elements have similar properties on the periodic table?
The elements in the same groups usually do. Elements in the same group have same number of valence electrons and hence have similar chemical and physical properties.
What does the arrangement of the periodic table help table scientists see?
Patterns in the elements’ properties. -Apex
Why are the elemets in the periodic table listed in ceratin groups?
The vertical "groups" group elements by chemical properties the horizontal "periods" group elements by the number of energy levels
What are families of elements with similar chemical properties called?
families of elements with similar chemical properties are called groups.
Why groups of periodic table have similar chemical properties?
The properties of chemical elements have a periodic trend.
Why are periodic tables called that?
Because the elements that have similar properties are arranged in groups - or 'periods'.
What sets of elements have similar physical and chemical properties?
Except noble gases the groups of elements in periodic table have the similar chemical properties but not the physical.
Elements in a have similar chemical properties?
a group of elements that have similar properties are arranged one on top of the other on the periodic table. These groups are also called families
What does the group number help tell you in columns?
Group number describes the number of valence electrons. It helps in estimating chemical properties of that element.For example-group-1 elements have 1 valence electronThe group number of an element is equal to the number of valence electrons. The number of valence electrons is responsible for the chemical properties. So the chemical properties of the element can be determined by the group number.
Multiple choice questions on periodic table of element?
- the rational arrangement of chemical elements - elements in groups - elements in periods - atomic number - prediction of chemical and physical properties of elements
In which two groups are the elements most similar in their chemical properties?
1 and 2
What are the differences between groups and periods?
Groups consist of elements listed in the same column. These elements share similar chemical properties, such as number of valence electrons. Periods are the rows of elements. These elements do not share chemical properties, as periods are organized by increasing atomic number (number of protons).
Elements that are in a vertical column in the periodic table that tend to share similar chemical properties and characteristics are called a?
The vertical elements are called groups. They have similar chemical properties.
What is true about elements in each groups?
They have the same number of valence electrons and so have similar reactivity and similar properties.
What was the problem with Dobereiner's periodic table?
Dobereiner is remembered for what were called "Dobereiner's Triads" which are groups of three elements having similar chemical properties. This is a forerunner of the periodic table, but it is not actually a table, and it does not offer any explanation for the chemical similarities observed within the triads. Mendeleev's Periodic Table of the Elements shows the relationship of every element to every other element, and explains why they all have the chemical properties that they have.
