1. The atomic number tells you the ___ for an element. A. Number of protons B. Atomic mass C. Number of neutrons Charge of the Fundamental Particles The fundamental particles of an atom are protons, neutrons, and electrons. These are known as...
name 200.59 average atomic mass the atomic weight is a measurement of the total number of particles in an atom's nucleus including both protons and neutrons. so the first step is to locate the atomic mass on the periodic table, and round the value to the nearest whole number. 200.59 ...
The number of protons in a nucleus atom is equal to the total amount of positive charge of the nucleus. So the number of protons in the nucleus... See full answer below. Learn more about this topic: Atomic & Mass Number | Overview & Difference ...
The atomic weight of an atom, or the molecular weight of a molecule, is its mass relative to that ofa___ atom. This is essentially equal to the number of protons plus neutrons that the atom or molecule contains. A oxygen B hydrogen C helium D carbon 相关知识点: 试题来源: 解析 B ...
atomic number 1.Or proton number (Z) The number of protons in the nucleus of an atom. If not electrically charged, this is equal to the number of electrons in its shells. 2.The number of protons in the nucleus of an atom. Dictionary of Unfamiliar Words by Diagram Group Copyright © ...
The number of protons in an atom is unique to each element. For example,carbonatoms have six protons,hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical be...
The atomic number (原子序数) is equal to the number of electrons per atom or, what is equivalent, the number of protons (质子) per nucleus.相关知识点: 阅读 文言文阅读 文言题类 文言文阅读——翻译 试题来源: 解析 [答案]原子序数等于每个原子的电子数或者相当于每个原子核的质子数。
·Across the period,the atomic radii decrease .This is because the number of protons (the nuclear charge) and the number of electrons increases by one every time you go an element to the right. .The elements in a period all have the same number of shells (so the shielding effect is the...
If the number of protons and electrons are equal, the charge on this atom is (a) ___. If the number of electrons and protons are not equal, this atom is called an (b) ___. An atom with an atomic number of 10 and a mass number of 24 would have . A) 14 electrons B) 24 ...
