The atoms increase in size, because they gain more electron energy shells.
What else can I help you with?
What happens to the size of the atoms as you move down the periodic table in group 7?
Down the group, size increases. Because number of shells increases.
Is chlorine larger in atoms than bromine?
No, chlorine is smaller in size compared to bromine. This is because as you move down a group in the periodic table, the atoms increase in size due to additional electron shells being added. Chlorine is above bromine in the same group (halogens) on the periodic table.
As you go down in group 1 why do the atoms get bigger in cross section?
As you go down Group 1, the atoms get bigger due to the addition of energy levels (shells) in which electrons can be found. This results in more electron-electron repulsions, causing the atoms to expand in size. Additionally, the increased number of electron shells further away from the nucleus leads to a larger atomic radius.
When the atoms of the elements of group 0 are compared in order from top to bottom the attractions between the atoms of each successive element?
The attractions between the atoms of each successive element in Group 0 (noble gases) generally decrease from top to bottom. This is because as you move down the group, the atomic size increases, leading to weaker interatomic forces, such as London dispersion forces. These weaker forces result in lower attractions between the atoms.
Do the halogens become more reactive or less reactive as they go lower down the group?
Halogens become less reactive as you go down the group. This is because atomic size increases down the group, making it more difficult for the larger atoms to gain electrons and react with other substances. Conversely, smaller halogen atoms are more reactive because they can more easily gain electrons and form bonds with other elements.
What happens to the size of the halogen atoms as you go down the group?
atomic number increases
What happens to the size of the atoms as you move down the periodic table in group 7?
Down the group, size increases. Because number of shells increases.
What happens to the size of the atoms as you go down this group?
Atomic size decreases as one moves from bottom to top in a group. The elements get smaller because they have less stuff in them.
What happens to the atomic structure as you go down any group?
Down a group, the atomic size (energy level / shells) increases.
What element in Group 1 has the largest atoms?
Cesium, which is in Group 1 of the periodic table, has the largest atoms. This is because as you move down a group, the atomic size generally increases due to the addition of more electron shells.
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.
Describe how the reactivity of Group 7 Halogens changes as you move down the column Explain why this happens?
The reactivity of Group 7 halogens decreases as you move down the column from fluorine to iodine. This is because atomic size increases down the group, leading to weaker intermolecular forces of attraction between atoms. As a result, it becomes harder for the halogens to gain an extra electron and they become less reactive.
Why Thermal stability increases when going down the group?
Thermal stability increases down a group because the atomic size increases, leading to weaker intermolecular forces and greater distance between atoms, making it harder for the atoms to come together and react. Additionally, the lower electronegativity of larger atoms down the group makes them less likely to form covalent bonds with other atoms, enhancing their thermal stability.
Is chlorine larger in atoms than bromine?
No, chlorine is smaller in size compared to bromine. This is because as you move down a group in the periodic table, the atoms increase in size due to additional electron shells being added. Chlorine is above bromine in the same group (halogens) on the periodic table.
What happens to atoms size as you move down the periodic table in the noble gases?
The atomic size would increase as you move down anywhere on the table-even the noble gases and as you move to the right. This happens because the higher the atomic number, the higher the protons and electrons, and the more repulsive force. The protons keep pushing out the electrons, therefore making a bigger atom!:D
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
As you go down in group 1 why do the atoms get bigger in cross section?
As you go down Group 1, the atoms get bigger due to the addition of energy levels (shells) in which electrons can be found. This results in more electron-electron repulsions, causing the atoms to expand in size. Additionally, the increased number of electron shells further away from the nucleus leads to a larger atomic radius.
