Atoms lose their neutrality when electrons are either lost or gained. Atoms that have lost or gained electrons are called ions. Neutral atoms have the same number of protons, neutrons and electrons. More » Science Chemistry Atoms & Molecules

Atoms are neutral because they have same number of positively charged particles, protons, and negatively charged particles, electrons. The amount of charge in a single proton is equal to the amount of charge possessed by... More »

Atoms are typically found in a neutral state, which means they have an equal number of electrons and protons. Electrons are negatively charged particles while protons are positively charged. More » Science Chemistry Atoms & Molecules

The phosphorus atom in phosphorus trichloride possesses a lone pair of electrons, which causes the atom to be polar. The three chlorine atoms bonded to the phosphorus atom exert a pull on the molecule's electrons, while ... More »

With an atomic number of 4, beryllium has four electrons: two electron shells surround the atom's nucleus and two electrons in each shell. Beryllium is a rigid metal with an atomic mass of 9.0122. It is lightweight but s... More »

An atom is the basic unit of a chemical element, and the two main regions of this structure are the nucleus and electrons. The nucleus is positively charged, while the electrons are negatively charged and orbit the nucle... More »

To draw a Bohr model of an atom, first find the number of protons, neutrons and electrons in the atom from its atomic weight and atomic number. After that, place the neutrons and the protons in the nucleus, and draw the ... More »
