why are there equal numbers of protons and electrons?

The atomic number is the number of protons in an atom of an element. ... By definition, atoms have no overall electrical charge. That means that there must be a balance between the positively charged protons and the negatively charged electrons. Atoms must have equal numbers of protons and electrons.

Answer and Explanation: All atoms of an element have the same number of protons. The number of protons in an element is a primary identifier known as its atomic number.

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges, this means that atoms are have no overall electrical charge.

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds.

Protons and neutrons make up the nucleus of an atom. All protons are identical to each other, and all neutrons are identical to each other. Protons have a positive electrical charge, so they are often represented with the mark of a "+" sign.

Understand that isotopes of an element have different mass numbers but the same number of protons. Using the Periodic Table, find the atomic number of the element. The atomic number equals the number of protons. In a balanced atom, the number of electrons equals the number of protons.

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges, this means that atoms are have no overall electrical charge. For example, the atomic number of sodium is 11. Every sodium atom has 11 protons and 11 electrons.

All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom. ... The number of protons within the atom's nucleus is called atomic number and is equal to the number of electrons in the neutral (non-ionized) atom.

Electrons are critical to the workings of electricity (notice a common theme in their names?) In its most stable, balanced state, an atom will have the same number of electrons as protons.

Atoms having the same number of protons (and therefore the same number of electrons) but different numbers of neutrons are called isotopes of the element in question. Thus, the isotopes of an element have the same atomic number but differ in their atomic mass number.

The number of protons in an atom of an element is its atomic number . ... all atoms of a given element have the same number of protons. atoms of different elements have different numbers of protons.
75858
Different isotopes of an element generally have the same physical and chemical properties. That's because they have the same numbers of protons and electrons.

An atom contains equal numbers of protons and electrons . Since protons and electrons have equal and opposite charges , this means that atoms are neutral overall.

A. Atomic Number Equals Electrons or Protons The atomic number equals the charge on the nucleus. It therefore also equals the number of protons in the nucleus and also equals numerically the number of electrons in the neutral atom. The atomic number has the symbol Z.

The number of protons in an atom is called its atomic number. This number is very important because it is unique for atoms of a given element. All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms.

Each atom, therefore, can be assigned both an atomic number (the number of protons equals the number of electrons) and an atomic weight (approximately equaling the number of protons plus the number of neutrons).

So the positive charges of protons are balanced by the equal number of electrons. ... ions loose electron to attain nearest noble gas electronic configuration , and become stable. But atoms does not have filled valence shell. Thus ions are more stable than atoms.
