Protons, Neutrons, and Electrons. Atoms contain protons, neutrons and electrons. Protons have a mass of 1 AMU, and a positive charge. Neutrons have a mass of 1 AMU, and no electrical charge. Electrons have very little mass compared to protons and neutrons, and they have a negative charge. Answer and Explanation:

8 protons and 10 electrons b. 16 protons and 8 electrons c. 8 protons and 8 electrons d. 10 protons and 8 electrons e. none of the above How many protons and electrons do the following ions contain? a) Ba^{2+} protons electrons.

Aluminum has 13 protons, 13 electrons, and 14 neutrons. To determine this, look first at the atomic number for aluminum, which

Protons:Protons are subatomic particles that, together with neutrons, form the nucleus of an atom. Protons are larger and more massive than electrons, and carry a positive charge, {eq}1.6\times 10 ...

35 protons, 35 electrons, 46 neutrons b. 35 protons, 35 electrons, 116 neut A neutral isotope has a mass number of 65 and 36 neutrons. Identify the element symbol of this isotope and determine the number of protons and electrons.

How many protons, neutrons, and electrons are contained in an atom of the isotope bromine-79? How many protons, neutrons, and electrons in ^{90}Sr^{2-}? How many protons, neutrons, and electrons are in chlorine-35? State its atomic number and mass number. An ion has a charge of -1, has 17 protons and 17 neutrons. What is it's mass number (A)?

(a) 45 protons. 21 neutrons, 48 electrons (b) 21 protons, 24 neutrons, 18 electrons (c) 45 protons. 24 neutrons, 48 electrons (d) 21 protons, 24 neutrons, 21 electrons (e) 24 proton What is the mass number of an atom with 3 protons, 4 neutrons, and 3 electrons?

2008年5月18日 · Protons and neutron are created by a process called Pair production. Pair production refers to the creation of an elementary particle and its antiparticle via Quantum Chromodynamics (QCD). Pair production can only occur if the photon has an energy exceeding the twice the rest mass(me) of an electron (1.022 MeV); the same applies for the ...

a) 12 protons, 23 neutrons, and 23 electrons b) 239 protons, 145 neutrons, and 239 electrons c) 94 protons, 239 neutrons, and 93 electrons d) 94 protons, 145 neutrons, and How many neutrons are in the nucleus of the atom 3517Cl?

2010年7月22日 · The discovery of protons, neutrons, and electrons provided evidence for the existence of atoms, which were first proposed by Greek philosophers in ancient times. Later experiments, such as the development of the periodic table and the discovery of isotopes, further confirmed that atoms are composed of protons, neutrons, and electrons.
