Sulfur possesses 16 electrons in its ground state. The first shell of sulfur has 2 electrons. The next shell has 8 electrons. The third and final shell of sulfur has 6 electrons. The electronic configuration is written as:
1s², 2s², 2p⁶, 3s², 3p⁴
This means that sulfur exhibits a valency of -2, which is true in many cases.
Answer:
Tin
Explanation:
Tin is an element which belongs to the carbon family in the periodic table. It lies in group 14 of the periodic table i.e. IV a.
The symbol of Tin is Sn. Tin has 50 electron in total. Its atomic number is 50. The 50 electrons of tin are divided in its five energy shells. The outer most or the valence shell contains 4 electrons in the ground state.
The number of electrons present per shell in tin is : 2, 8, 18, 18, 4.
The electronic configuration of tin is : [Kr] 4d¹⁰5s²5p²
Answer:
A is the answer. Chemical changes happen when atomic bonds are broken or created during chemical reactions. Hence, in this case, it involve changes to molecular structure.
- Change in states are physical changes.
- When salts are dissolved in water, you can use Distillation to separate them. Distillation is a physical change as well.
- Dissolving is just physical change.
Explanation:
The statement that is true of a chemical change among the statements given in the question is "It involves changes in the molecular structure". The correct option among all the options that are given in the question is the first option or option "A". I hope the answer has actually come to your help.
