Why do atoms always contain the same number of electrons
An atom is defined as being neutral by convention, adding the neutral part is unnecessary. If it has gained or lost electrons than the atom becomes an 'ion': either a 'cation' (a loss of electrons resulting in a positive net charge), or an 'anion' (a gain in electrons causing a negative net charge).... In the center is the Nucleus where you find the positive Protons and neutral Neutrons. In orbit around the nucleus are the Electrons. These are found in a series of orbits (depending on the atom) with differing numbers of electrons as seen below.
how do you know if an atom/element is neutral or not
If electrons are lost or gained by a neutral atom, then the result is that a charged particle is formed - called an ion. For example, Sodium (Na) has 11 protons and 11 electrons. However, it …... It follows that in a neutral atom: no of electrons = no of protons So, if an oxygen atom (atomic number = 8) has 8 protons, it must also have 8 electrons; if a chlorine atom (atomic number = 17) has 17 protons, it must also have 17 electrons.

Atoms are neutral; they contain the same number of protons as electrons. By definition, an ion is an electrically charged particle produced by either removing electrons from a neutral atom to give a positive ion or adding electrons to a neutral atom to give a negative ion. how to do a support letter ” In an uncharged, neutral atom, the number of electrons orbiting the nucleus is equal to the number of protons inside the nucleus. In these atoms, the positive and negative charges cancel each other out, leading to an atom with no net charge.

10/12/2018 · For example, Ca 2+ has a +2 charge, therefore, it has 2 fewer electrons than a neutral calcium atom. Calcium’s atomic number is 20, therefore this ion has 18 electrons. 3. Add the charge to the atomic number if the charge is negative. If the charge is negative, the ion has gained electrons. To determine how many total electrons there are, add the amount of charge to the atomic number. In how to tell if you re overdosing on coke An atom can be an ion, but not all ions are atoms. The difference between an atom and an ion has to do with net electrical charge. An ion is a particle or collection of particles with a …

How To Tell A Neutral Atom
An atom is stable because of a balanced nucleus that does not contain excess energy. If the forces between the protons and the neutrons in the nucleus are unbalanced, then the atom is unstable.... If the forces between the protons and the neutrons in the nucleus are unbalanced, then the atom is unstable....
- All elemental atoms contain the same number of protons and electrons, thus giving them a neutral charge. An ion is any element that contains a different number of protons and electrons resulting in either a positively or negatively charged atom. Identifying whether or not an element is an ion is a very simple process. Identify the charge of the element. The charge of an element is equal to the
- STABLE AND UNSTABLE ATOMS. After reading this section you will be able to do the following: Define the terms "strong force" and "binding energy." Explain what is meant by a stable atom and and an unstable atom.
- If an atom has only one proton, we know it's a hydrogen atom or, said differently, it's an atom of the element hydrogen. Similarly, a vehicle with two wheels is always a bike, just like an atom with two protons is always a helium atom , or an atom of the element helium .
