Only electrically neutral atoms.
Yes, the number of electrons in an atom determines its chemical properties and therefore what kind of element it is. The arrangement of electrons in an atom's energy levels is responsible for the element's characteristics such as reactivity and bonding behavior.
an atom becomes neutral if the atom has an equal number of electrons and protons.
An atom has a nucleus composed of protons and usually neutrons as well (there is only one kind of atom which has no neutrons, which is the hydrogen 1 isotope) and it also has electrons surrounding the nucleus, with the same number of electrons as the number of protons in the neutrons.
What do you mean by "normal" atom? There are ions: charged atoms or molecules. It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. But I think a "normal" atom, would be a neutral one. A neutral atom has the same amount of protons as electrons, therefore have no net charge.
An atom is uncharged or neutral when the number of protons in its nucleus is equal to the number of electrons surrounding the nucleus. This balance of positive and negative charges results in the atom having no overall charge.
There are three kinds of "dots" in a atom. Electrons, neutrons, protons. Electrons have a negative charge, neutrons have no charge, and protons have a positive charge. The numbers of dots represent what kind of atom it is, as on the periodic table of the elements. The atomic number and mass tells you how many electrons/neutrons/or protons there are.
Neutron are what keeps the nucleus together. Protons are what decides the kind of element which the atom is and the electrons decide the charge of the atom.
anion
The atomic number, which is the number of protons in the nucleus, determines what kind of atom it is.
No , an atom always has equal numbers of protons and electrons. If it has more charges of one kind than another is called an ion. Obviously this is caused by the number of protons and electrons compared to each other. If it has more positive charges, it has more protons than electrons, making it a positive ion. If it is a negative charge, it has more electrons than protons, it is a negative ion.
Protons, neutrons and electrons
Zinc has 30 protons since its atomic number is 30. This also means that it has 30 electrons to balance the positive charge from the protons. The number of neutrons in an atom of zinc can vary based on the isotope, but a typical zinc atom has around 35 neutrons.
