Answer:
Explanation:
Given elements:
Sodium
Fluorine
The ion Na⁺ is made up of 10 electrons, its electronic configuration is:
1s² 2s² 2p⁶
Ion F⁻ is made up of 10 electrons, its electronic configuration is:
1s² 2s² 2p⁶
These ions do not form +2 because they cannot attain stability by losing or gaining two electrons.
Sodium atom is made up of one valence electron. If it loses one electron, it will be isoelectronic with Neon.
Fluorine has 7 valence electrons, to attain stability, it must gain one electron to form an octet. This way it will be isoelectronic with Neon.
Losing or gaining two electrons will not make the elements attain stability.
Answer:
Average Atomic Mass = 10.81
Explanation:
Data Given:
Atomic Mass of ¹⁰X = 10 amu
Relative Intensity of ¹⁰X = 23 %
Atomic Mass of ¹¹X = 11 amu
Relative Intensity ¹¹X = 100 %
It means that if there are 123 atoms of this mystery element then then 23 will be of an isotope with atomic mass of 10 amu and the remaining 100 will be of an isotope with atomic mass of 11 amu.
So, we will now calculate the total mass of all elements as;
Total Mass = (23 × 10) + (100 × 11)
Total Mass = (230) + (1100)
Total Mass = 1330 amu
Then, we will calculate the average mass as,
Average Atomic Mass = 1330 / 123
Average Atomic Mass = 10.81
Answer:
They mostly dissolve in water, and they are poor conductors of heat.
Answer:
Honey
Explanation:
i know why but at the same time i don't. i know that water, tea, and milk are very fluid however honey is sticky and isn't AS FLUID as the others.
Therefore, honey as the highest viscosity.
