(a)(i)Accept for the relative mass of electron[1] All relative charges are correct[1] All relative masses are correct(ii) The mass of an atom is concentrated in the nucleus of an atom. The electrons are of negligible mass.The nucleus is positively charged(due to the protons), and the...
. It therefore seemed desirable to find whether matter in which there is an excess of neutrons is electrically neutral. We have found that the charge on an argon atom (18 protons, 18 electrons and 22 neutrons) is not greater than 8×10−20eand that on a nitrogen molecule (14 protons, ...
An atom has 75 protons, 74 electrons, and 112 neutrons. What is the charge of the atom? What has 8 protons and 10 electrons? Is a hydrogen ion a proton? What is an atom that has a charge is called? What is the charge of a neutral object?
We know that all objects are made up of atoms and atoms are composed of smaller particles called protons, electrons and neutrons. Protons and neutrons are found in the nucleus of an atom and eletrons are found in an area outside often described as an electron cloud (see what are atomic ...
The atom is the smallest unit on Earth. It is the basic component of any type of matter. It cannot be broken down or sectioned. Protons, neutrons and electrons make up the subatomic particles of an atom. The three subatomic particles determine the overa
Answer to: A Se ion has a mass number of 78 and a charge of 2-. Determine the number of neutrons, protons, and electrons in this ion. By signing...
Each element on the periodic table has protons, neutrons, and electrons which makes each element an atom. Each element has its own number of protons (positive), neutrons (no charge), and electrons (negative). The number of protons and electrons is equal. A neutral atom is an atom or ...
Molecules contain atoms and atoms are the smallest units of matter that retain the properties of the chemical element. The three basic subatomic particles are neutrons, protons, and electrons. It is within the atom that we encounter the elementary charge. Electric charge is carried by the ...
1 翻译一下可以吗1.An atom is made up of positive charges (protons),neutral charges (neutrons) and negative charges (electrons).The protons and neutrons are found within the nucleus of an atom,while we learnt in P08 Curious glow that the electrons are found in different energy levels about...
