Why do elements in the same group have similar properties?
The elements in a group on the periodic table have similar properties. The properties are similar because the elements within a group have the same number of elec- trons in their outer energy level. Atoms often take, give, or share electrons with other atoms.
What two elements that belong to the same group?
Size of their atoms
Why do elements in the same group have similar chemical properties?
Elements in the same group in the periodic table have similar chemical properties. This is because their atoms have the same number of electrons in the highest occupied energy level. Group 1 elements are reactive metals called the alkal.
What do you know about elements in the same group?
Elements in the same group tend to show patterns in atomic radius, ionization energy, and electronegativity . From top to bottom in a group, the atomic radii of the elements increase. Since there are more filled energy levels, valence electrons are found farther from the nucleus.
In chemistry, a group is a vertical column in the periodic table of the chemical elements. Each element within a group has similar physical or chemical properties because of its atom’s outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
What is calcium and oxygen called?
Calcium oxide (CaO), commonly known as quicklime or burnt lime, is a widely used chemical compound.
What elements have the similar properties?
Elements in the same group of the periodic table have similar chemical properties. Elements can be classified as metals, metalloids, and nonmetals, or as a main-group elements, transition metals, and inner transition metals.
What element is the same as calcium?
Calcium is a chemical element with the symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium.
What are the Group 17 elements called?
halogen
halogen, any of the six nonmetallic elements that constitute Group 17 (Group VIIa) of the periodic table. The halogen elements are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).
Why are members of Group 1 called alkali metals?
The Group 1 elements are called the alkali metals. All the Group 1 elements are very reactive . They must be stored under oil to keep air and water away from them. Group 1 elements form alkaline solutions when they react with water, which is why they are called alkali metals.
Does copper react with oxygen?
Heated copper metal reacts with oxygen to form the black copper oxide. The copper oxide can then react with the hydrogen gas to form the copper metal and water.

What are the physical and chemical properties of calcium?
Calcium is an alkaline earth metal, it is a reactive pale yellow metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth’s crust and the third most abundant metal, after iron and aluminium.
What is the atomic number of the element calcium?
Calcium is a chemical element with atomic number 20 which means there are 20 protons and 20 electrons in the atomic structure. The chemical symbol for Calcium is Ca. The atom consist of a small but massive nucleus surrounded by a cloud of rapidly moving electrons. The nucleus is composed of protons and neutrons.
