Atoms are made from three basic particles: protons, neutrons and electrons
Neutron and protons make up nucleus. Electrons revolve around the nucleus
The cloud around an atom's nucleus is called an electron cloud. An electromagnetic force binds electrons inside an electrostatic potential well, which surrounds the nucleus.
The nucleus of an atom is always positively charged. The magnitude of the positive charge is proportional to the atomic number of the element. For instance, the charge on a nucleus of Hydrogen is +1 or +1.6 x 10-19 C as the atomic number of Hydrogen is 1. The charge on a nucleus of carbon (at. no. =6) is +6 or +6 x 1.6 x10-19 C

All kinds of incandescent lamp, and all types of light bulb contains filament. But there are several kinds of filament applied each type of light bulb.
Speaking very generally, most atoms consist of a dense nucleus which contains protons and neutrons, and an electron cloud away from the nucleus which contains electrons.
Atoms are made of a nucleus, which contains subatomic particles called neutrons and protons, and electrons, which orbit the nucleus in certain areas.
The nucleus,which contains electrons(-) and protons(+)
The nucleus of an atom contains protons and neutrons, while the electron cloud surrounds the nucleus and contains the electrons. The nucleus is positively charged and is much smaller in size compared to the electron cloud. The electron cloud determines the size of the atom and contains most of the atom's volume.
Boron is an element and therefore contains boron atoms.
An atom's nucleus contains protons and neutrons, which are the subatomic particles that make up the majority of an atom's mass. The nucleus is the central core of an atom where these particles are located, surrounded by the electron cloud.
All hydrogen atoms have 1 protron in the nuclues and 1 electron outside the nucleus.
The proton in an atoms nucleus has a positive charge. The nucleus of an atom contains protons an neutrons whilst the electrons "orbit" the nucleus and have a negative charge.
Most of the mass of a potassium atom is located in its nucleus, which contains protons and neutrons. The electrons in the electron cloud surrounding the nucleus have significantly less mass compared to the nucleus.
An atom contains protons, neutrons, and electrons, electrons being the one that moves around the nucleus. The other two are in the nucleus.
The central core of an atom is called the nucleus. It contains protons and neutrons, which account for most of the atom's mass. Electrons orbit around the nucleus in specific energy levels.
The nucleus of the cell contains the genome.
