kkurt [141]3 years ago
3 0
An atom is the smallest particle of an element that can take part in a chemical reaction. Its structure has a nucleus and energy levels. The nucleus of an atom contain protons and neutrons whereas the energy levels contain electrons.
For a particle containing 56 protons (atomic number) and 82 neutrons has 56 electrons since the number of protons and neutrons in an uncharged atom are equal.
The atom in this case is must be an isotope of Barium since barium has an atomic number of 56 .

The overall charge of an atom is ________ if the number of electrons is ________ than the number of protons.
miss Akunina [59]
The overall charge of an atom is positive if the number of electrons is less than the number of protons. Electrons are negatively charged particles while protons are positively charged particles. If there are less electrons as compared to the number of protons in an atom, then naturally the overall charge of the atom would be positive since there are excess protons. Another case would be that the overall charge of an atom is negative if the number of electrons is greater than the number of protons. An atom having more electrons than the number of the protons present would lead to a negative value of the charge since there are excess electrons.
