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 are all reactive non-metals. They react with metals to form metal halides, and with hydrogen to form acidic hydrogen halides.
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 ...
Explains the trends in atomic radius, electronegativity , first electron affinity, melting and boiling points for the Group 7 elements in the Periodic Table ...
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.
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.
The properties of elements in group VII can be predicted using their position in the group. ○ E.g. Using the trend in reactivity, predict the element in group ...
