What else can I help you with?
What happens to an atom if there is an excess or a shortage of electrons?
If an atom has an excess of electrons, it becomes negatively charged and is called an anion. If it has a shortage of electrons, it becomes positively charged and is called a cation. Both types of charged atoms are called ions.
What is important about the number of electrons in the outside surface of an atom?
It keeps the atom at a constant charge. Too little electrons means the atom is positively charged, while too many means the atom is negatively charged.
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
How many charged particles are in a Polonium atom?
The neutral atom of polonium has 84 protons and electrons.
One helium atom has how many electrons?
It depends on the charge of the atom/ion however in a no-charged state Helium will have 2 electrons. If the Helium is charged negatively will have more. If it is charged possitively (up to 2+) it will have less. As Helium is a noble gas, it is rarely found in a charged state!
When at atom is charged it is called an ion. How many electrons are in O2-?
O2- has gained two extra electrons, giving it a total of 10 electrons.
How many atoms are in atoms?
One! An atom is not made up of other atoms, but has a nucleus of a positively-charged proton and a neutrally-charged neutron. It is surrounded by a network of positively-charged particles called electrons. (sorry, NEGATIVELY charged particles called electrons!)

The number of electrons should = the number of protons.
When an atom is charged it is called an ion how many electrons are in oxygen?
A neutral oxygen atom has 8 electrons. When oxygen becomes an ion, it can gain 2 electrons to become O2-, losing the neutral 8 electrons to become a total of 10 electrons in the ion.
How many charged particles are in a Polonium atom?
The neutral atom of polonium has 84 protons and electrons.
If an atom is neutrally charged and has 10 protons then how many electrons does it have?

When at atom is charged it us called an ion how many electrons are in 02?
O2 has 16 electrons. Each oxygen atom has 8 electrons, and since O2 is a molecule made of two oxygen atoms, the total number of electrons is 16.
One helium atom has how many electrons?
It depends on the charge of the atom/ion however in a no-charged state Helium will have 2 electrons. If the Helium is charged negatively will have more. If it is charged possitively (up to 2+) it will have less. As Helium is a noble gas, it is rarely found in a charged state!
How many electrons are in a positively charged hydrogen atom?
None. A hydrogen atom has one proton and one electron (no neutron). Removing the electron leads to just a proton, no electrons.
If an atomic number is 11 how many electrons dose the atom have?
if it is not charged - 11.
