What else can I help you with?
What are the names and atomic numbers of the halogens?
Fluorine = 9 Chlorine = 17 Bromine = 35 Iodine = 53 Astatine = 85
How does the reactivity of halogens change as you go down group 7?
As you go down group 7 (halogens), reactivity decreases. This is because as you move down the group, the outer electron shells of the halogens are further away from the nucleus, making it harder for them to gain an electron and react with other elements. Additionally, the atomic size increases which leads to weaker intermolecular forces between the atoms.
What is an example of atomic numbers?
Atomic number= number of protons. Hydrogen atomic number=1
What is the correlation of ionization energies to atomic radii for the elements?
There is an inverse relationship between ionization energy and atomic radius: as atomic radius increases, ionization energy decreases. This is because as the distance between the nucleus and valence electrons increases, the attraction between them weakens, making it easier to remove an electron.
What is the trend in melting points as you go down the group of halogens?
The trend in melting points as you go down the group of halogens is that they generally increase. This is due to the increasing number of electrons and atomic size which results in stronger van der Waals forces between the atoms, leading to higher melting points.
What is Relation between atomic and mass numbers?
mass number=atomic number+no. of neutrons
What are the names and atomic numbers of the halogens?
Fluorine = 9 Chlorine = 17 Bromine = 35 Iodine = 53 Astatine = 85
What is the difference between the atomic number and the valence number of an atom?
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 difference between the atomic number of an element and the 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.
What is the relation of knowing the atomic radius in your daily lives?
There is no relationship between the atomic radius and you knowing it.
What is halogens atomic number?
The halogens are located on the left of the noble gases on the periodic table. These five toxic, non-metallic elements make up Group 17 of the periodic table and consist of: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Is there a correlation of electron affinities to atomic radii?
The relation between electron affinity and atomic radius is inversely proportional.
What trends the periodic table should be expected as the atomic number decreases in the halogens?
Halogens with lower atomic number are more reactive and less dense. Also iodine is solid, bromine liquid and the first halogens are gases.
Why is there a pattern between melting point and atomic radius?
A relation doesn't exist.
What is the deference between the atomic number?
they describe the same thing. Proton numbers are unique to each element, as are atomic numbers
