Protons are subatomic particles that, along with neutrons, comprise the nucleus or central portion of an atom. The rest of the atom consists of electrons that orbit the nucleus, much as Earth orbits the sun. Protons can also exist outside an atom, in the atmosphere or in space. In 1920,...
Remember, an isotope is a form of a chemical element that has the same number of protons in its atomic nucleus but a different number of neutrons. The most common isotope of helium on Earth is helium-4, which does not have any known or potential uses as an energy source. Helium-3, in...
Which element has 16 neutrons, 15 protons, and 15 electrons? What element has 6 protons, 8 neutrons, and six electrons? What element has 4 protons 5 neutrons and 2 electrons? What is the atomic mass of an atom that has 6 protons, 6 neutrons, and 6 electrons? What isotope has 18 prot...
Protons are also heavy particles and they have a positive charge. Electrons are light particles and they are negatively charged. There are many important features that arise from considering the number of these particles in each atom. For example, the number of protons an atom has will determine...
The northern lights occur when electrically charged particles from the sun — mostly electrons andprotons— slam into Earth's upper atmosphere at speeds of up to 45 million mph (72 million kph), but our planet's magnetic field protects us from the onslaught. ...
In between the clouds and the ground, the atoms in the air undergo changes; most important to our discussion, electrons move farther away from protons, creating an environment that allows electrons to move around freely. In other words, the air becomes a good conductor. Once the air is ...
The protons get sucked across a ‘proton exchange membrane’ (PEM), while the electrons – unable to cross the PEM – get sent through a circuit, power the motor and come out the other end to combine with the oxygen in the air which has been passed through the cathode. H2 becomes to...
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...
It has six protons, six electrons, and six neutrons, so its atomic number is 6 and its relative atomic mass is 12. But there's also another form of carbon called carbon-14, with six protons, six electrons, and eight neutrons. It still has an atomic number of six, but its relative ...
What happens if an atom has more electrons than protons? It becomes a negatively charged ion, called an anion. 6 Why are protons crucial to an element's identity? Because the number of protons determines the atomic number and thus the element's identity. 4 What role do protons play in th...
