All atoms of the same element contain the same number of protons in the nucleus. This is what defines the element and gives it its unique characteristics.
The atoms of ALL elements contain at least one protons. The atomic number of each element is a count of how many protons atoms of that element contain. Thus, in answer to your question, there are NO metals that do not contain a proton.
All atoms of the specified data contain 38 protons, 38 electrons (assuming they are not ions), and 50 neutrons. They are atoms of the element Strontium.
The number of protons in the nucleus of an atom determines an element's atomic number. In other words, each element has a unique number that identifies how many protons are in one atom of that element. For example, all hydrogen atoms, and only hydrogen atoms, contain one proton and have an atomic number of 1. All carbon atoms, and only carbon atoms, contain six protons and have an atomic number of 6. Oxygen atoms contain 8 protons and have an atomic number of 8. The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same.
Every atom categorised within the same periodic element should contain the same atomic number, which represents the number of protons within the nucleus. Each element is unique in how many protons reside in one atom, for example all oxygen atoms would contain eight protons and hydrogen atoms would only contain one proton.
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
Each atom of the element magnesium contains exactly 12 protons.
In respect to different elements, no they don't, in respect to like atoms of one particular element, yes they do. The electrons are the particles that vary from like atoms of the same element. When the electrons and protons are uneven within an atom, you have a radioactive element.
All the lithium atoms contain the same number of protons.
All atoms of the same element have the same number of protons. Atoms of different elements have different numbers of protons. The number of protons determines the element.
All elements contain protons.
