Bonding between 2 hydrogen atoms is 'covalent bond'.
Hope this helps you.
Answer:
b. Bakelite
Explanation:
Bakelite -
Bakelite is a form if plastic , and is the very first plastic synthesized .
The handles of the cooking utensils are used to hold the utensil firmly , and hence need not turn hot while cooking , and need to be strong enough to take care of the food .
Hence , the handle should be of the material which is poor conductor of heat and strong .
Hence , bakelite is used for making the handle.
Because they want you to get wet
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:
c. ₆¹²C and ₆¹³C
Explanation:
Properly writing the given options:
a. ₁¹H and ₁¹H⁺
b. ₇¹⁴N and ₇¹⁴N³⁻
c. ₆¹²C and ₆¹³C
Electrons are the crux of chemical reactions. These negatively charged subatomic particles determines chemical properties of atoms and how they combine with other atoms.
Atoms having the same number of electrons especially in their valence shells shares similar chemical properties.
From the problem above, we have been given some information about the atom.
The mass number is given by the superscript before the symbol of the atom and it signifies the sum of the number of protons and neutrons in the atom.
The atomic number is shown by the subscript and it denotes the number of protons in the atom.
For neutral atoms that has not lost or gained any additional electron, the atomic number is the same as the number of electrons.
The superscript after the atom is the charge on the particle. It represents the number of electrons lost or gained by the atom.
In {c. ₆¹²C and ₆¹³C}, the atom is in a neutral state. Here the atomic number which is 6 is the number of protons in the atom. This is also the number of electrons in the atom. Therefore, the two atoms would have similar chemical properties and behavior.
This is not so for the others as their number electrons are different.
