they all have smilar characteristics and similar atomic numbers.
In each group of elements, The elements will react in a way that is chemically similar. For example, all alkali metals (lithium, sodium, potassium, rRubidium, caesium, and francium) react vigorously with water
The group of elements with two valence electrons in each period is known as the alkaline earth metals. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They are located in group 2 of the periodic table.
True. Elements with similar properties are typically found in the same group (vertical column) on the periodic table due to a similar arrangement of their outer electrons and valence shell. Elements in the same period (horizontal row) have different properties but share the same number of electron shells.
All the elements in group 6 are called the transition metals. This is also true for groups 3-12.
True. Mendeleev organized the elements into the periodic table based on their atomic weight and similar chemical properties. He noticed that elements with similar properties tended to occur at regular intervals, leading to the periodicity of the elements.
It is true.
what property does each of the elements have
Each group has a group number.
In each group of elements, The elements will react in a way that is chemically similar. For example, all alkali metals (lithium, sodium, potassium, rRubidium, caesium, and francium) react vigorously with water
elements in a group have the same number of valence electrons
It is true, all are solids.
The group of elements with two valence electrons in each period is known as the alkaline earth metals. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They are located in group 2 of the periodic table.
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
No, elements in the same column are in the same family.
True. Elements with similar properties are typically found in the same group (vertical column) on the periodic table due to a similar arrangement of their outer electrons and valence shell. Elements in the same period (horizontal row) have different properties but share the same number of electron shells.
Yes, this affirmation is true.
Each column is a group of chemical elements.
