What is the difference between subatomic particles and elementary particles?
Subatomic particles are proton, neutron, electron; these particle are some examples of the large group of elementary particles.
What are electrons in a atom?
In the electron cloud. In the electronic shells which vary from one element to another They surround the nucleus in a cloud-type formation. This can help you during your science mid-term so pay attention!
What has the most mass protons or electrons?
Neutron has the highest mass in this group. Proton mass is just less than that of neutron. Electron and positron are anti particles to each other. They have opposite quality only due to charge polarity. Both have same mass. Mass of electron is some 1836 times less than that of proton. Please note down the different quantities. Proton, photon and positron.
Why is the atomic radius of iodine is greater that the atomic radius of fluorine?
The atomic radius of an atom generally increases as you move down a group in the periodic table due to the addition of more electron shells. Iodine is located below fluorine in the same group (Group 17), so iodine has more electron shells compared to fluorine, leading to a larger atomic radius.
Why is ethanol a weaker acid than water?
Ethanol is a weaker acid than water because the presence of the alkyl group (-CH3) in ethanol increases electron density around the oxygen atom, making it less likely to donate a proton compared to water. This decreased ability to donate a proton makes ethanol a weaker acid than water.
Why does electron withdrawing groups increase acidity?
Assuming the groups are conjugated to the acid/base groups: An acid wants to lose a proton. When it loses a proton, you form an anion (or a neutral molecule, but when talking about electron donating/withdrawing groups, you assume there is a charge). The more stable the anion, the more easily the proton comes off, and the more acidic it is. A base is the opposite. A base gains a proton to become cationic. The more stable the cation, the more likely it is to pick up a proton, and the more basic it is. An electron withdrawing group can stabilize an anion (and thus make something more acidic) and an electron donating group can stabilze a cation (and make something more basic). The opposites also hold true: an electron donating group can destabilize an anion and make something less acidic, and vice versa for bases.
How many protons does the hydrogen element has?
Hydrogen always has 1 proton. If it had two, it would then become Helium. The fact that it is a Hydrogen ion, just means that it is not electrically neutral. Since the proton is what defines the atom, the Hydrogen atom must be missing an electron, leaving the atom with a net positive charge of +e.
Which is a stronger acid cresol or phenol?
Phenol is more acidic because cresol has +I effect of CH3 grup as you know acidity is reciprocal of +I effect. OR Cresol has electron donating methyl group, whih reduces its electron defficiency of the phenol group and hence acidity.
What is the family of hydrogen?
Hydrogen is placed in group 1, along with alkali metals
What is the base in a reaction?
The base in a chemical reaction is the species that either (a) accepts a proton, (b) produces an OH- ion, or (c) is an electron donor.
Why is Hydrogen in group one of the periodic table?
Hydrogen is placed in group 1 of the periodic table due to its one valence electron, which it can lose to form a cation with a +1 charge, similar to the alkali metals in that group. However, hydrogen's properties are different from typical group 1 elements due to its diatomic nature and other unique characteristics.
Is OCH3 an electron-donating or electron-withdrawing group?
OCH3 is an electron-donating group.
