Why Do Elements In The Same Group Have Similar Properties
Condition
- malleable Can be pulled or stretched into thin wire by mechanical force without breaking.
- Physical Property Any measurable property whose value describes the state of a physical system.
- malleable Can be forged into thin sheets; capable of being stretched or shaped by hammering or by the pressure of rollers.
In chemistry, a group is a vertical column in the periodic table of chemical elements. There are 18 groups in the standard periodic table, including d-block elements but excluding f-block elements. Each element in a group has the same physical or chemical properties because the atom has an outermost electron shell (most of the chemical properties are governed by the orbital position of the outermost electron).
General physical properties
The physical property of a pure substance can be defined as anything that can be observed without changing the identity of the substance. Observations usually include some sort of numerical measure, although sometimes there is a more qualitative (non-numerical) description of the attribute. Physical properties include things like:
- Color
- Brittleness
- malleability
- Flexibility
- People’s Spirits
- Density
- Magnetism
- Stiffness
- Atomic number
- Specific heat
- Heat of vaporization
- Heat of fusion
- Crystal configuration
- Melting temperature
- Melting point
- Heat conductivity
- Steam pressure
- Tends to dissolve in various liquids

For example, lithium, sodium, potassium, rubidium, cesium, and francium all have a single electron in the s orbital, while every element in the group that includes fluorine has the ns2np5 valence electron configuration, where n is the period. This means that elements of a group often have similar chemical reactions and may have similarities in physical properties.
Boiling and Melting Points
Before discussing the melting points of different elements, it should be noted that some elements exist in different forms. For example, pure carbon can exist in the form of diamond, which has a very high melting point, or in the form of graphite, whose melting point is still high but much lower than diamond. | Top Q&A Different groups show different trends in boiling and melting points. For Groups 1 and 2, the boiling and melting points decrease as you move down the group. For the transition metals, the boiling and melting points mostly increase as you move down the group, but they decrease for the zinc family. In the main group elements, the boron and carbon families (Groups 13 and 14) decrease in boiling and melting points as you move down the group, while the nitrogen, oxygen and fluorine families (Groups 15, 16 and 17) tend to increase both. High gases (Group 18) decrease in boiling point and their melting point decreases with the group These phenomena can be understood in relation to the types of forces that hold the elements together. For metals, metal-bonding interactions (electron sharing) become more difficult as the elements get larger (towards the bottom of the table), causing the force holding them together to become weaker. However, as you move along the board, polarity and van der Waals interactions prevail, and as larger atoms are more polar, they tend to exhibit stronger intermolecular forces and thus It has higher melting and boiling points.
Metal character
Metallic elements are shiny, usually gray or silver, and conduct heat and electricity. They are malleable (can be forged into thin sheets) and malleable (can be stretched into wire). Some metals, such as sodium, are soft and can be cut with a knife. Others, such as iron, are very hard. Non-metallic atoms are dull and conduct electricity poorly. They are brittle when solid, and many are gaseous at STP (standard temperature and pressure). Metals give away valence electrons when bonding, while non-metals tend to take electrons.One metal and one non-metal To the left is sodium, a very metallic (plastic, malleable, conductive) element. On the right is sulfur, a very non-metallic element. Metallic properties increase from right to left and top to bottom across the board. Non-metallic properties follow the opposite pattern. This is due to other trends: ionization energy, electron affinity and electronegativity. You’ll notice a jagged line running through the periodic table starting between boron and aluminum – this is the separation between metallic and non-metallic elements, with some elements close to the line representing the characteristics of each. element. The metals are located towards the left and center of the periodic table, in the s, d, and f blocks. Poor metal and metallic metal (part metal, part non-metal) are in the lower left of the p block. Non-metallic substances are on the right side of the table.
