24 сент. 2024 г. · Reactivity of Group 7 non-metals increases as you go up ... density so it is useful to know the trends in properties going down the group ... |
15 апр. 2024 г. · The melting and boiling points of the Group 7 elements increase going down the group which indicates that the elements become less volatile. |
The group 7 elements tend to have a major group oxidation state (+7), although this trend is markedly less coherent than the previous groups. Like other groups ... |
Elements in the same group of the periodic table show trends in physical properties, such as boiling point. They have the same number of electrons in their ... |
This is because the molecules are larger further down the group, so the electron density increases and therefore, there are increased Van der Waals forces. |
Generally, the densities of all of the elements increase as you go down the group. The reason may be that as you go down a group, the atomic structure increases ... |
The halogens 1. Have higher melting points and boiling points. 2. Have a higher density. 3. Are bad conductors of heat and electricity. 4. Have bigger atoms. |
