An atom that loses electrons has more positive charges (protons) than negative charges (electrons). It is positively charged. An atom that gains electrons has more negative than positive particles. It has a negative charge. A charged atom is called an "ion." Some materials hold their electro...

A lightning bolt with 10 kA strikes an object for 15 mus. How much charge is deposited on the object? A uniform electric field of magnitude 1.0 x 10^2 N C^-1 exists between two conducting plates, one of which is positively charged and the other of which is nega...
aIt is remarkable that the C-terminal domains(CTDs) of class B Hsfs are completely different. For the group of the most conserved Hsfs in plants, ie, HsfB1, the CTD is positively charged, and AHA motifs are lacking. We have evidence that HsfB1 plays a special role in gene activation ...
the water while positively charged ions are attracted down the tube. The result is a net flow of positively charged ions that sets up an electric current. According to Dr Kostiuk no one has ever thought to use water to produce electricity in this way."The last time someone came up with ...
Hardly anyone can positively enjoy sitting in a train for more than a few hours. Train compartments soon get cramped and stuffy. It is almost impossible to take your mind off the journey. Reading is only a partial solution, for the monotonous rhythm of the wheels clicking on the rails soon...
[河南南阳六校 2023 高二期末联考 ]It had always been assumed that the rarity of lightning in ocean storms was due to cleaner air over the vast seas, but keen observations have shown that even highly polluted air is associated with reduced lightning at se a when se a spray aerosols(气溶胶)...
Reason : It is bourided to the nucleus. View Solution Assertion Mass of ion is slightly differed from its element. Reason Ion is formed, when some electrons are removed or added, so mass changes. View Solution Name the negatively charged and positively charged components of a nucleosome. ...
aIons can be positively charged (Anion) or negatively charged (Cation) as a result of the loss or gain of electrons during chemical reactions or exposure to certain forms of radiation 离子可以是正面地被充电的 (阴离子) 或消极地被充电的 (正离子) 由于电子损失或获取在对辐射的某些形式的化学反应...
