Are chemical properties of elements determined by neutrons?
No. The properties of elements are determined by the number of protons, which in turn determines the number of electrons.
What is the total number of elements in Group 17 that are gases at room temperature at standard pressure?
There are two that are gases, fluorine and chlorine.
What chemical properties of the elements are chiefly due on what?
The chemical properties of the elements are chiefly due to the number and distribution of the outer electrons that they have.
How is the periodicity of properties dependent upon the number of protons in an atom?
The number of protons is equal to atomic number. The periodicity of chemical properties depends on the outermost shell of electrons.
The periodic law states that the properties of elements will repeat when the elements are arranged by _______.?
If the elements are arranged in the order of their increasing atomic numbers, there properties are repeated in a periodic manner.
What is the total number of elements in period 2 that are gases at room temperature and standard pressure?
4
What is the total number of elements in group 17 that are gases at room temperature and standard pressure?
its either123or 4
Are chemical properties of elements determined by neutrons?
No. The properties of elements are determined by the number of protons, which in turn determines the number of electrons.
What determines the properties of elements?
the properties of elements are determined by the structures of their atoms.
Do any of the elements on the periodic table of elements have similar properties?
Elements in the same group have similar properties. The groups are made according to the properties of elements. Elements in a group have an equal number of valence electrons.
What is the total number of elements in Group 17 that are gases at room temperature at standard pressure?
There are two that are gases, fluorine and chlorine.
How does the modern periodic table arrange the elements?
In the modern version of the periodic table, the elements are arranged in increasing order of the atomic number. The chemical properties of an element can be predicted by its group. For example group 1 elements react violently to give away one electron to form +1 ions where group 18 elements are inert in standard temperature and pressure. This periodic table was introduced by Henry Mosley.
Are the elements of the periodic table arranged by their properties?
Elements are arranged by their atomic number. The properties are periodic when arranged in this manner.
How does the number of the outer energy level electrons relate to the properties of elements?
Elements whose atoms have the same number of outer electrons have similar properties..
How does the number of outer energy level electrons related to the properties of elements?
Elements whose atoms have the same number of outer electrons have similar properties..
How are elements indentified on the periodic table?
Elements in the table are identified by different things. What they are made of, atomic mass, and atomic number. Elements can also be identified by what state of matter they are at zero degrees Celsius and standard pressure which 1atm. The most current, standard table has 117 different elements.
What are the properties based on modern periodic table?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
