Question: What kind of atom has one less proton in its nucleus than does Helium? Atomic Number: {eq}\\ {/eq} An element is characterized by the number of protons in the nucleus of its atoms. If any two atoms have a different number of protons in their nuclei, then they b...
An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms. When an atom loses one or more...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer your...
Proton p 1 +1 Electron e 1/1836≈ 0.0005 ≈ zero -1 Neutron n 1 0(neutral) ≈ means "approximately equal to" The nucleus of an atom: Each atom has a nucleus at approximately the centre of its volume consisting of the two types of particles called protons and neutrons. Protons and ne...
A proton is a subatomic particle found in the nucleus of atoms that differs from the other subatomic particles (called neutrons) in the nucleus of most atoms because each proton has a positive charge of +1 (as opposed to neutrons, which have no charge).

Each proton in the nucleus of an atom has a tiny positive charge (electricity that stays in one place). We say it has a charge of +1 to make everything simple (in reality, a proton's charge is a long and complex number: +0.00000000000000000016021892 C, to be exact!). Neutrons have ...
Due to the nature of opposite charges attracting, atoms tend to have an equal number of protons and electrons, leaving the atom as a whole having a net charge of zero. However, if the atom either loses or gains an electron, it becomes an ion, and carries a charge. It will seek ...
What Is an Atom? The Legacy of Ancient Times Through the 19th Century The modern view of an atom has come from many fields of chemistry and physics. The idea of an atom came from ancient Greek science/philosophy and from the results of 18th and 19th century chemistry: concept of the atom...
An Al atom contains neutrons, protons, and electrons. What are the orbitals of an electron? What is the atomic number? If an atom has 1 proton, no neutrons, and 1 electron, what element is it, what is its mass, and what is its charge? A) Hydrogen, 1 amu, -1 charge B) Hydrogen...
The first building block is the neutron, a fusion of the energy of the electron with that of the proton, our third sub atomic particle. Now we can get an atomic nucleus of protons and neutrons. A ‘cloud’ of orbiting electrons adds space to the nucleus, creating the atom. Combining ...
