What else can I help you with?
If an atom has 19 protons and 20 neutrons how much electrons does it have?
It depends. From the given information about the number of protons, we can be sure that we are talking about potassium. The number of neutrons in this case won't matter. If the question emphasizes "atom" then we can be sure that the particle is neutral. Then we know that for the particle to be neutral, it has to have the same number of electrons as protons. However, potassium will not stay neutral for long if given a chance. It will lose an electron when bonding with others, to eventually have 18.
What Atomic number is the number of what subatomic particle?
Atomic number is equal to the number of protons and electrons (in a neutral atom).
What is the subatomic particle and the calculation derived from it that is not found in the periodic table?
Subatomic particles are protons, neutrons and electrons; the number of protons and electrons (in the neutral state) are equal to the atomic number of an element.
What is the number of electrons present in a neutral atom of each element 1 copper 2 chlorine?
Copper has 29 electrons.Chlorine has 17 electrons.
All elements on the periodic table are neutral because they have the ame number of electrons as what other particle?
PROTONS. Isotopes of an element may have a different number of neutrons.
What particle are always present in equal number in a neutral atoms?
protons and electrons
Number of electrons present in a neutral barium atom?
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which represents the number of protons and electrons in a neutral atom.
What are the number of electrons present in a neutral barium atom?
The barium atom (neutral) contain 56 electrons.
How many electrons are present in a neutral barium atom?
A neutral barium atom has 56 electrons. This is because the atomic number of barium is 56, which corresponds to the number of electrons it has when it is electrically neutral.
A particle of matter contains of 6 protons 7 neutrons and 6 electrons This particle must be a A neutral carbon atom B neutral nitrogen atom C neutral oxygen atom D neutral potassium atom?
A particle containing 6 protons, 7 neutrons, and 6 electrons is a neutral carbon atom. The number of protons determines the element, so 6 protons corresponds to carbon on the periodic table. The number of neutrons is added to determine the isotope, and the number of electrons balances the charge to make it neutral.
Which particle contains the greatest number of electrons F or Na?
The fluoride ion (F-) contains more electrons than the sodium ion (Na+), as fluoride has 10 electrons in its neutral state whereas sodium has 11 electrons in its neutral state. When fluorine gains an electron to become fluoride, it has one more electron than sodium.

How many electrons are present in an atom?
That depends on the element you are considering. For a neutral atom, the number of electrons = number of protons = atomic number
What is a unionized particle of an element?
A unionized particle of an element refers to an atom that has not gained or lost any electrons, thus maintaining a neutral charge. This means the number of protons in the nucleus is equal to the number of electrons orbiting the nucleus.
What is present in equal number in a neutral atom?
it is protons and electrons. your welcome and vote this best answer!
What Atomic number is the number of what subatomic particle?
Atomic number is equal to the number of protons and electrons (in a neutral atom).
What subatomic particle is responsible for whether or not an atom will be an ion?
Ionic charge is determined by the number of electrons in the atom. A neutral atom has the number of electrons equal to the number of protons in the nucleus. An ion is formed when there is a surplus or deficit in electrons
