Does electrically neutral atoms have equal numbers of electrons and protons?
Electrically neutral atoms simply possess the same number of electrons as protons. This gives the objects a balance of both type of charge. There are 11 electrons and 10 protons.
What is the number of electrons in a neutral atom equal to?
number of protons
The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom. This is known as the atomic number, Z. The removal or addition of electrons to a neutral atom creates ions that have a net negative or positive charge.
Do neutral atoms have equal numbers of protons and neutrons?
Each atom of an element contains the same number of protons, which is the atomic number (Z). Neutral atoms have the same number of electrons and protons. Each isotope of a given element has the same atomic number but a different mass number (A), which is the sum of the numbers of protons and neutrons.
Which of the following must be equal in a neutral atom?
The positive charge on a proton is equal in magnitude to the negative charge on an electron. As a result, a neutral atom must have an equal number of protons and electrons.
What elements are electrically neutral?
Since atoms are electrically neutral (they carry the same number of protons as electrons); then, the number of protons tells us the number of electrons an element has….Figure 2.1. 5 The main elements that compose the human body.

Why do atoms have equal numbers of protons and electrons?
Actually the proton and electron count of an atom are equal only when the atom is neutral in charge. The electrons are found in orbitals surrounding the nucleus. In order for the atom to remain electrically neutral the protons and electrons must balance each other.
Why do atoms contain equal numbers of protons and electrons?
Which subatomic particles must be present in equal numbers in an electrically neutral atom?
An atom has an equal number of electrons and protons and so is electrically neutral (i.e., has no electrical charge).
Are neutral atom has the same number of protons and electrons?
A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess.
Do neutral atoms have equal numbers of electrons and protons?
Atoms are made of protons, neutrons, and electrons. Protons carry a positive electrical change, while electrons are negatively charged, and neutrons are neutral. A neutral atom has the same number of protons and electrons (charges cancel each other out). An ion has an unequal number of protons and electrons.
What must a neutral atom have?
If a neutral atom has 2 protons, it must have 2 electrons. If a neutral atom has 10 protons, it must have 10 electrons. You get the idea. In order to be neutral, an atom must have the same number of electrons and protons.
What is the number of protons and electrons in a neutral atom?
The atom is neutral. The atom has 30 protons. Neutrality implies that all charges cancel. Protons are positively charged, and electrons are negatively charged. Therefore, a neutral atom has the same number of protons as electrons, no matter the number of neutrons. You have two charges, and two types of particles.
