shells or orbit
The "dense" central portion of an atom is called the nucleus. The nucleus of an atom contains neutrons and protons.
If you are talking about elements, they are electrons.
the layer of electrons surrounding the nucleus of an atom is called "shells"
Polonium's atomic number is 84. That means it has 84 protons and 84 electrons. However, none of these electrons are found in the nucleus, but rather outside of it in what is called the electron cloud.
They're called electrons.
Electrons orbit the Nucleus. the Nucleus contains protons and neutrons. The proton contains positive in charge (+) and Neutrons are neutral. (=) However, electrons are the ones with negative charge. (-)
The central area of an atom is called the nucleus. It contains protons and neutrons, which are tightly bound together. The nucleus makes up the majority of an atom's mass and is surrounded by a cloud of electrons.
The particles outside of an atom are called electrons :D
Electrons orbit the nucleus of an atom. They move in specific energy levels called electron shells. The nucleus contains protons and neutrons.
The centre of an atom is called the nucleus, and it contains only protons and NEUTRONSbut no electrons at all.
The three subatomic particles are the proton, the neutron, and the electron. Protons and neutrons are located inside the nucleus. Electrons are located outside of the nucleus in the electron cloud.
An element has a small case in the center called the nucleus. Inside the nucleus contains protons an nuetrons. Protons have a positive charge and nuetrons have a negative charge. On the outside and are energy levels that have electrons and are negatively charged
