What happens to the reactivity of halogens as you go down the group?
the reactivity of halogens goes on decreasing as we go down the group, because of increasing in atomic size of the respective element.
How does atomic mass indicated element reactivity?
Atomic mass does not directly indicate an element's reactivity. Reactivity is primarily determined by the number of electrons in the outer shell of an element (valence electrons). Elements with a full or nearly full outer shell (noble gases) are generally unreactive, while elements with few electrons in the outer shell (alkali metals) are highly reactive.
Why and how element are arranged in 4th period?
Increasing atomic number by 1
What is the relevance of increasing atomic numbers in the arrangement of elements?
By doing it this way, you can arrange them in a fashion in which you can predict their reactivity by the row that they're in. This is because they are lined up to account for a visualisation of how much of the energy level is filled with electrons
What is meant the atomic number of an element?
The atomic number of an element is the number of protons found in the nucleus of an atom of that element. It uniquely defines an element and determines its chemical properties. Elements are arranged in order of increasing atomic number on the periodic table.
What is the difference between the atomic number of an element and the number of valence electrons?
Describe the reactivity of halogens
What is the difference between the atomic number of an element and number of valence electrons?
Describe the reactivity of halogens

What is the reactivity for the halogens?
The reactivity of halogens decreases with increasing atomic number.
As the elements in Group 17 are considered in order of increasing atomic number the chemical reactivity of each successive element decreases increases or remains the same?
As you move down Group 17 (halogens) from top to bottom, the reactivity decreases. This is due to the increasing atomic size and electron shielding, making it more difficult for the outer electron to be gained by the lower elements in the group, thus decreasing their reactivity.
How does atomic mass indicated element reactivity?
Atomic mass does not directly indicate an element's reactivity. Reactivity is primarily determined by the number of electrons in the outer shell of an element (valence electrons). Elements with a full or nearly full outer shell (noble gases) are generally unreactive, while elements with few electrons in the outer shell (alkali metals) are highly reactive.
Can you describe how the reactivity of group 1 elements varies with increasing atomic number?
With increasing atomic number, the lone valence electron gets further away from the nucleus and is thus less tightly bound. It thus wants to lose the electron even more so and thus INCREASES in reactvity
What is the difference between the atomic number and the valence number of an atom?
Describe the reactivity of halogens
If you add a proton to an element what happens to it?
Adding a proton to an element changes its atomic number, resulting in a new element. This can affect its chemical properties and reactivity.
Where on the periodic table is the element found?
The location of an element on the periodic table is determined by its atomic number, which in turn dictates its placement based on electron configuration and chemical properties. The element's position on the periodic table can provide information about its characteristics and reactivity with other elements.
