The period of an element can be determined by what?
The period of an element can be determined by its electron configuration, specifically the highest energy level that contains electrons. The period corresponds to the number of electron shells in the atom's structure. Each period represents a new energy level or shell being filled with electrons.
The first element in a period is always an active?
That is not true. The first element in a period may be active or inactive, depending on the specific electron configuration of the element. For example, the first element in period 1, hydrogen, is not considered an active element.
Which element in period 4 has the highest electronegativity?
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
The atomic weight of an element is determined by what?
The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass of the element.
What element is located in group 15 and period 2?
The element phosphorous (P) is located in group 15, period 2.
Why is the period of an element determined by an electron configuration?
The period of an element is determined by electronic configuration.Period is same as the number of energy levels of the element.
The period of an element can be determined by what?
The period of an element can be determined by its electron configuration, specifically the highest energy level that contains electrons. The period corresponds to the number of electron shells in the atom's structure. Each period represents a new energy level or shell being filled with electrons.
How can you predict and element's group and period?
Group No = No.of valence electrons in the outer configuration period No = principle quantum No.(n)of the last shell of outer configuration Eg:carbon EC=1s2 2s2 2p2 No.of valence electrons=4, indicates G.No.is IV n=2, indicates period No. is 2 chlorine EC=3s2 3p5 valence electrons=7,so G.No. is VII n=3,so period No is 3
What is an element is determined by the number of?
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
The atomic number of an element is determined by the number of?
The atomic number of an element is determined by the number of protons within it's nucleus.
Who determined the number of protons in each element?
The number of protons in each element is determined by the atomic number of the element. The atomic number corresponds to the number of protons in the nucleus of an atom. This number is unique to each element and is determined by the arrangement of electrons and protons in the atom.
What is the identity of an element determine by?
The identity of an element is determined by the number of protons.
He lightest element in period 2?
Helium is a period 1 element.
Is the atomic number of an element determined by its number?
Protons. This determines what material the element is.
what period is the element he in?
He is in period 1.
How is the identity of the element determined?
the number of its protons
How is the atomic mass of an element determined?
The atomic mass of an element is determined by calculating the weighted average of the masses of its isotopes, taking into account their relative abundance.
