1 and 3 only because metal are easily to loss electron while non metal are difficult to loss electron that's why it called heavy elements.
Answer:
The answer to your question is: Includes sulfur and gain two electrons
Explanation:
Includes Chlorine This option is wrong, Chlorine belongs to group VII.
Includes Sulfur This option is true, Group VI includes Oxygen, Sulfur, Selenium, Tellurium.
Gain 2 electrons
. This option is true, Elements in group VI have six valence electrons so they gain to electrons to become estable.
Tend to form +2 ions This option is wrong, this elements form -2 ions
Have 5 valence electrons This option is wrong, this elements have 6 valence electrons.
Answer:
[Kr] 4d10 5s2 5p4 is the electronic configuration for tellurium.
Electrons per shell: 2,8,18,18,6
Atomic number: 52
Symbol: Te
Answer:
Valence electron pairs are the total sum of lone pairs and bond pairs in the molecule. The electrons possess negative charge on them. They repel each other due to the presence of same charge. The lone pairs repel other electrons strongly, which are present around the central atom.
