What are the properties of elements and how are they organized?

The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

What are the properties of the elements in the periodic table?

Periodic trends are specific patterns in the properties of chemical elements that are revealed in the periodic table of elements. Major periodic trends include electronegativity, ionization energy, electron affinity, atomic radii, ionic radius, metallic character, and chemical reactivity.

What are the five characteristics of liquid?

  • liquid have a fixed volume but no fixed shape.
  • liquids can be compressed. large pressure is required to compress them.
  • liquids have lesser densities than solids.
  • intermolecular forces of attraction is weaker than solids.
  • they have considerable space between the particles.

Which is not a property of a gas?

The densities of gases are much larger than those of corresponding liquids. It is NOT a property of gases. Density is equal to mass divided volume. Since gases have larger volumes, their densities are lower than those corresponding to liquids.

Can gases be compressed?

Gas. The atoms and molecules in gases are much more spread out than in solids or liquids. They vibrate and move freely at high speeds. Gas can be compressed much more easily than a liquid or solid.

Which states of matter are fluid?

Fluids (Liquids and Gases) Liquids and gases are called fluids because they can be made to flow, or move.

Does the sun make fire?

Answer: The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. People, including scientists, sometimes say that the Sun “burns hydrogen” to make it glow.
