Which two particles that make up atoms have about the same mass? (Select all that apply.) A. Protons B. Electrons C. Neutrons The positron is a particle with the same mass as an electron but charge +e. A positron in a bubble chamber mov...
What is the formula for the ion which has 17 protons and 18 electrons? ACl BCl− CAr+ DAr−Submit Question 2 - Select One A species has 16 protons, 18 electrons and 16 neutrons. Find the species and its charge. AS− BSi2+ CP3− DS2−Submit Question 3 - Select One The nit...
Atoms are the building blocks of all existing substances. An atom contains a nucleus, which has protons andneutrons. Electrons circle around the nucleus inorbitals. In addition, there are other small subatomic particles in the nucleus. Most of the space in an atom is empty. The attractive forc...
• Electrons are considered as elemental particles. In other words, electrons cannot be divided into smaller components or substructures. • All the ions have sub-components. For example, polyatomic ions contain various atoms; atoms can be further sub-divided into neutrons, protons, electrons, e...
Positron emission and electron capture and are two types of nuclear processes. Although they result in changes in thenucleus, these two processes take place in two different ways. Both these radioactive processes occur in unstable nuclei where there are too manyprotonsand fewerneutrons. To solve ...
Alpha decay and Beta decay are two types of the radioactive decaying. The third type is gamma decay. All matter is made up of atoms that are made up of electrons, protons and neutrons. Protons and neutrons reside inside a nucleus while electrons revolve in orbits around the nucleus. While...
Figure 01: Electrons in Different Atomic Orbital Clouds An electron occurs in an atom as a subatomic particle, and other major subatomic particles are protons and neutrons. Typically, the mass of an electron is about 1836 times smaller than the mass of a proton. When considering the quantum me...
Atoms of the same kind have similar protons and electrons. Same type of atoms may differ due to the number of neutrons present, and these are known as isotopes. Atoms can join with other atoms in various ways, thus form thousands of molecules. All elements have a diatomic or polyatomic arr...
atoms have both chemical and physical properties of its particular chemical element. An atom is extremely small; the size is around 100 pm. It consists of an atomic nucleus containing protons and neutrons. This nucleus is surrounded by a cloud of electrons. Protons, neutrons and electrons are ...
