How are the elements oxygen and calcium different on the periodic table?
Oxygen is a nonmetal element found in group 16 of the periodic table, while calcium is a metal found in group 2. Oxygen has an atomic number of 8, while calcium has an atomic number of 20. They have different physical and chemical properties, with oxygen being a reactive gas and calcium being a reactive metal.
Which element has an atom with 20 electrons?
Calcium is the element that has the atomic number 20.
What conclusion can be drawn from the statement that an element has high electron affinity high electronegativity and a high ionization energy?
The element is likely a nonmetal with a strong tendency to gain electrons in a chemical reaction, has a high attraction for shared electrons in a compound, and requires a significant amount of energy to remove an electron from its outer shell. These characteristics suggest it is likely a reactive element that tends to form negative ions in chemical reactions.
Is Calcium reactive or nonreactive?
reactivity of any element depends on its form.Ca reacts in its Ca+2 form and forms CaCo3 (Calcium carbonate)CaSo4(calcium sulphate) etc.
What metallic element in period 4 has 20 electrons?
Calcium (Ca) is the metallic element in period 4 with 20 electrons.
What is an reactive nonmetal?
A reactive non metal is an element that can gain the electrons or is more electronegative

What is an element that is highly reactive gaseous nonmetal?
Chlorine and fluorine, with fluorine more reactive. Some would also include oxygen. (The two remaining halogens are not gaseous at room temperature.)
If calcium is not a mineral what is it?
Calcium is an element, silvery metallic, soft, and reactive.
Which element is more reactive calcium or pottasium?
Potassium.
Is fluorine classified as metal nonmetal or mettaloids?
Fluorine is classified as a nonmetal. It is a highly reactive, gaseous element that belongs to the halogen group in the periodic table.
Which nonmetal of the periodic table has 10 electrons?
The element Neon
Is fluorine the most reactive nonmetal?
With greater ionization energy, nonmetals have greater reactiveness. This is because they don't want to lose electrons at all! They will instead gain electrons to complete the octet.This proves true in the element Fluorine.
Is Calcium reactive or nonreactive?
reactivity of any element depends on its form.Ca reacts in its Ca+2 form and forms CaCo3 (Calcium carbonate)CaSo4(calcium sulphate) etc.
How many electrons do the calcium?
Calcium is a metal element. There are 20 electrons in a single atom.
