How many protons are there in a silver atom? How many protons, neutrons, and electrons does silicon have? A neutral beryllium atom has four protons and five neutrons. How many electrons does it have? How many protons, neutrons, and electrons are there in an atom of O-17?
So carbon 12. We know that it has the proton number, by definition, is 6. And the neutron number, 6 from 12 is 6. So it has 6 protons and 6 neutrons. 所以碳12,我们知道它有质子数,根据定义,那就是6,而电子数,12减6等于6,所以它有6个中子。
Chapter 3 Atoms and Elements Do these steps on the front of the worksheet Element Identities. Atomic Particles Particle Charge Mass # Location Electron -1 Atomic Structure Walk Around Move and label the protons, neutrons, and electrons to build an atom of each of the following elements. ...
Protons and neutrons make up the nucleus and electrons orbit them in a cloud.Answer and Explanation: The mass number is not the number of protons. The mass number is the number of protons added to the number of neutrons. The mass number can be found......
An atom is made up of three subatomic particles: protons, neutrons, and electrons. Inside the nucleus of an atom, the positively charged protons and the neutrally charged neutrons are found. Surrounding the nucleus are the negatively charged electrons. The balance between...
The atom is the smallest representative unit of a single chemical element and it contains some numbers of protons, neutrons and electrons. The number of protons for an element is fixed and represented by its atomic number. The number of neutrons can vary, which is the basis for isotop...
Protons have a positive charge, and weight one atomic unit. They are the main factor in determining what identity an element is Neutrons also weight one atomic unit, but have no charge. They are responsible for "gluing" the nucleus together, ensuring that the positive charges on the proton...
Give the number of protons and electrons in S^2- and Cu^2+. Identify the atom or ion that has 28 electrons, 30 protons, and 35 neutrons. Identify the atom or ion that has 8 electrons, 8 protons, and 8 neutrons. Identify the atom or ion that has 18 electrons, 15 protons, and 16...
