What is the atomic number of the element? View Solution (i) If an atom contains one electron and one proton, will it carry any charge or not ? (ii) On the basis of Thomson's model of an atom, explain how the atoms is electrically neutral. View Solution...
一道英文的物理题When a proton captures an electron,a photon with anenergy of 13.6 eV is emitted.What is the frequency of thisphoton?Does it lie in,above,or below the visible range?答案 当一个质子捕获一个电子时,会发射出一个具有13.6电子伏能量的光子,请问这个光子的频率是多少?它是否在可见光...
Together, protons and electrons form an atom'snucleus. A proton has a positive charge that counters the electron's negative charge. When an atom has the same number of protons and electrons, it is in a neutral state. Electrons are unique from the other particles in multiple ways. They exis...
Add one proton, one neutron, and one electron and you get an atom of beryllium (symbol Be).See how it works? In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and...
What Is The Difference Between An Electric And A Magnetic Dipole? AnElectric Dipoleis formed from a substance that possesses two equal electric charges of opposite sign separated by a small distance. The best example of an electric dipole is an atom with one electron and one proton (Hydrogen)...
An uncharged Sodium atom contains 11 electrons and 11 protons. What will be the charge of the atom if three of the electrons are removed? a. +3e b. -3e c. +8e d. -8e The magnitude of the charge of the electron is: a. About 1000 times the charge of...
Proton p 1 +1 Electron e 1/1836≈ 0.0005 ≈ zero -1 Neutron n 1 0(neutral) ≈ means "approximately equal to" The nucleus of an atom: Each atom has a nucleus at approximately the centre of its volume consisting of the two types of particles called protons and neutrons. Protons and ne...
Protons and neutrons have approximately the same mass. However, one proton is about 1,835 times more massive than an electron. Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes ...
A carbon atom has six protons and six, seven, or eight neutrons, depending on the isotope of carbon. Isotopes are atoms of an element with the same number of protons but different numbers of neutrons. The number of protons (also called the atomic num...
