electron. Determine the number of electrons in the atom of interest. The number of electrons in the atom is equal to the atomic number of the element. Write the electron configuration for the element in question. Fill the orbitals of the atom in the order 1s, 2s, 2p, 3s, 3p, 4s, 3d...
Determine how many protons and electrons you'll need to draw. The amount of electrons in an atom is tied to the amount of protons. However many protons you have, that's how many electrons you'll need. To determine the number of protons, you just look at the atomic number. The atomic ...
How to use a balance to find the mass of an object? Explain. Measurement: Measurement is a way to determine the magnitude of a desired trait of a given object. These traits include the mass of an object, the volume of an object, temperature, and time. Answer and Explanation: ...
Because these extremely small masses expressed in scientific notation are difficult to work with, chemists have developed a method of measuring the mass of an atom relative to the mass of a specific atomic standard. 由于非常小的质量在科学中难以表达,化学家发展了测量原子相对质量的方法,我们需要一个...
Neutrons are neutrally charged subatomic particles found in the nucleus of an atom along with the positively charged protons. Together, protons and neutrons contribute equally to the mass number of the atom. Answer and Explanation:1 Become a Study.com member to unlock this answer!Create you...
1. Tally the number of atom of each element on each side. Balancing the Equation for Photosynthesis 2. Choose an element to begin with. It is usually a good idea to begin with the element that has the most atoms. In this case that is the 12 hydrogen atoms in the product side. The ...
[translate] aThe atomic mass of an element indicates how heavy, on average, an atom of an element is when compared to an atom of another element 元素的原子质量表明多么重,平均,元素的原子是,当与另一个元素时原子比较[translate]
Each one has a tiny, positively charged nucleus, balanced by a cloud of negatively charged electrons. These determine the atom’s properties. Split an atomic nucleus open and you’ll find subatomic particles called protons and neutrons. The simplest atom, hydrogen, has just one proton and no ...
Each element on the periodic table has an atomic mass -- an approximation of the mass of a single atom of that element. Because atoms are so small, a specific unit is used to measure the mass of small quantities of atoms. Very large quantities of atoms a
Subtract the atomic number from this atomic weight to work out the number of neutrons in your atom. Helium has an atomic weight of 4, which means it has two neutrons. 00:0000:00 Brought to you by Sciencing Molar Mass Calculator Common Compounds Periodic Elements Chemical Formula He ...
