Protons have a positive (+1) charge, which balances the negative (-1) charge of the electrons that surround the nuclei of atoms. Protons have a relative mass of 1, which is the same as the relative mass of neutrons. The number of protons in an atom is called the 'Atomic Number' of...
It basically set forth the idea that gravity is a predictable force that acts on all matter in the universe, and is a function of both mass and distance. The theory states that each particle of matter attracts every other particle (for instance, the particles of "Earth" and the particles ...
In any atom, like charges repel one another, and opposite charges attract one another. This is why two protons repel each other and so do two electrons, but a proton and an electron attract each other. In an element, the numbers of electrons and protons are equal. Moreover, since they...
The net charge of an atom is zero. An atom consists of protons, electrons and neutrons. Protons have a positive charge, electrons have a negative charge and neutrons have zero charge. Since atoms are neutral, the numbers of protons are equal to the number of electrons. In a given m...
Gravity: A universal force Four fundamental forcesact upon us every day. Thestrong forceand the weak force operate only inside the centers ofatoms. The electromagnetic force rules objects with excess charge (likeelectrons,protons, and socks shuffling over a fuzzy carpet), and gravity steers objects...

The total number of protons and neutrons added together is called the relative atomic mass. Hydrogen has a relative atomic mass of 1, while helium's relative atomic mass is 4 (because there are two protons and two neutrons inside). In other words, an atom of helium is four times heavier...
This means the sun is producing more sunspots, solar flares and coronal mass ejections (CMEs) — massive bursts of solar material that can supercharge auroras on Earth. During this period, the northern lights can appear brighter, more colorful and be visible farther south than usual. The ...
wherea = 1,2,3is elided from all but the Yukawa term. For a fixed triplet generationi, the eigenstates of electric charge are given by the combinations [69] \begin{aligned} \Sigma _{Ri}^\pm \equiv \frac{\Sigma _{Ri}^1 \mp i\Sigma _{Ri}^2}{\sqrt{2}}, \quad \Sigma _{Ri...
Protons carry a positive charge, while electrons have a negative charge. This difference is crucial because it ensures that atoms, under normal circumstances, remain electrically neutral when the number of protons equals the number of electrons. 9 The mass of a proton is considerably larger than ...
