All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. … Atoms are neutral in electrical charge because they have the same number of negative electrons as positive protons (Table 2.4. 1).
Also question is, are all protons the same?
All protons are identical. For example, hydrogen protons are exactly the same as protons of helium and all other elements, or pure substances. However, atoms of different elements have different numbers of protons. … The number of protons in an atom determines the electrical charge of the nucleus.
Furthermore, do all elements have the same atomic number?
Each element has its own atomic number, which is equal to the number of protons in its nucleus. Isotopes of an element contain different numbers of neutrons. Elements are represented by an atomic symbol.
How are atoms of the same element similar and different?
ISOTOPES AND ATOMIC MASSES
For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
Is atom the same as element?
An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction.
Why are all atoms of an element the same?
The atomic number is the same as the number of protons. … The atomic mass is the sum of the number of protons and neutrons. For ions (which may either have a positive or negative charge), only the number of electrons are being changed. If the ion is negative it means that an electron has been added to the configuration.
Why do all atoms of an element have the same atomic number although they have different mass numbers?
All atoms of a chemical element have the same atomic number (number of protons in the nucleus) but may have different mass numbers (from having different numbers of neutrons in the nucleus). Atoms of an element with the same mass number make up an isotope of the element.
