Answer:
b) [Kr] 5s² 4d¹⁰ 5p⁵
Explanation:
Properties of iodine:
Iodine is present in group seventeen.
It is halogen element.
Its atomic mass is 127 amu.
Its atomic number is 53.
It is present in solid form.
It is crystalline in nature.
It is very corrosive and has pungent odor.
It can not react with oxygen and nitrogen.
Electronic configuration:
I₅₅ = 1s² 2s² 2p⁶ 3s³ 3p⁶ 4s² 3d¹⁰ 4p⁶ 5s² 4d¹⁰ 5p⁵
Abbreviated electronic configuration:
I₅₅ = [Kr] 5s² 4d¹⁰ 5p⁵
Abbreviated electronic configuration is shortest electronic configuration by using the noble gases.
Answer:
D. All of the above
Explanation:
E = MC² is a common equation in physics.
E is energy
M is mass
C is the speed of light
The law was stated by Albert Einstein.
- From this law, it was shown that energy is released when matter is destroyed.
- Mass and energy are equivalent as seen in nuclear reactions where mass is converted to energy.
- Mass and energy is usually conserved in any process and this is a subtle modification of the law of conservation of matter and energy.
- Most of these postulates apply to nuclear reactions which generally do not follow some precepts of chemical laws.
Answer: Would be D. Fe and S have an ionic bond, while S and O have covalent.
