What is the relative size of the 3 subatomic particles?
Protons and neutrons are about the same size and are larger than electrons. Protons and neutrons have a size of about 1 femtometer (10^-15 meters), while electrons are about 1000 times smaller.
What atom has the same number of protons and electrons?
Naturally, all elements have the same number of electrons and protons.
What is the relationship between the electrons and neutrons and protons?
Electrons are negatively charged, smaller than neutrons and protons, and orbit around the nucleus. Neutrons have no charge, are about the same size as protons and are found in the nucleus. Protons have a positive charge, are about the same size as neutrons and are found in the nucleus.
Do all atom have the same number of electrons or protons?
No, only atoms of the same element have the same number of protons and electrons.
What is an atom called when you have the same numbers of protons as electrons?
On average, in any atom, you will have the same number of electrons and protons.
How does a neutron have same number of protons and electrons?
a neutron is neutral. it doesn't have the same number of protons and electrons, but an atom that is neutral does. A neutron has the same mass as a proton but it doesn't have a chrge. Protons are positively charged and electrons are negatively charged.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
Do protons nuetrons and electrons all have about the same mass?
Protons and neutrons have about the same mass, but electrons are much, much lighter.
What substance has the same number of protons and electrons?
All neutral atoms have the same number of protons and electrons as they are electrically neutral.
If an atom has 49 protons how many electrons does it have?
A neutral atom with 49 electrons will have 49 protons. The number of protons and electrons are always the same in a neutral atom. If the number of protons is not matched by the number of electrons, then the atom is charged and is called an ion. Further, if protons outnumber electrons, the atom is positively charged and is a positive ion. For situations where electrons outnumber protons, the opposite is true. The element with 49 protons in it is indium, by the way.
Do an isotope have extra electrons or protons?
Isotopes have the same number of protons (which determine the element) but may have a different number of neutrons. They do not have extra electrons or protons; the number of electrons in an isotope is the same as the number of protons, ensuring the overall charge is balanced.
If the number of electrons and protons are not the same what do you call this?
When the number of electrons and protons are not the same in an atom, it becomes an ion. An atom becomes positively charged if it loses electrons (more protons than electrons), and negatively charged if it gains electrons (more electrons than protons).
