What else can I help you with?
A neutral atom contains 5 neutrons and 4 protons how many electrins does it contain?
Protons: 5 Neutrons: 7 Electrons: 5
What is the subatomic particles charges of calcium atom?
The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus.The protons have a positive charge, the neutrons have no charge, and the electrons have a negative charge.
How many protons electrons neutrons are in a molecule of carbon dioxide how many in a molecule of calcium nitrate?
Carbon Dioxide has the formula of CO2, which means 1 Carbon atom and 2 Oxygen atom per CO2 molecule. Carbon12 has 6 protons, 6 neutrons and 6 electrons per atom. Oxygen has 8 protons, 8 neutrons and 8 electrons per atom. One CO2 molecule contains 22 protons, 22 neutrons and 22 electrons. Calcium Nitrate has the formula of Ca(NO3)2. Calcium contains 20 of each. Nitrogen contains 7 of each. Oxygen contains 8 of each. Per molecule there are 1 calcium, 2 Nitrogen and 6 oxygen. Therefore: 20 + (2x7) + (6x8) = 20 + 14 + 48 = 72 protons, 72 Neutrons and 72 electrons. I hope that answers your question.
What is the atomic structure of an oxygen atom?
An oxygen atom has 8 protons, 8 neutrons, and 8 electrons. It has a nucleus containing protons and neutrons, surrounded by electron shells. Oxygen's electron configuration is 2-6, meaning it has 2 electrons in the inner shell and 6 in the outer shell.
What is the difference between an oxygen 16 atom and an oxygen 18 atom?
The main difference between an oxygen-16 atom and an oxygen-18 atom is their atomic mass. Oxygen-16 has 8 protons, 8 neutrons, and 8 electrons, while oxygen-18 has 8 protons, 10 neutrons, and 8 electrons. This difference in neutron number gives them different atomic masses and slightly different chemical behaviors.

How many protons nuetrons and electrons does a helium at have?
A helium atom has 2 protons, 2 neutrons, and 2 electrons.
Which of the has an electric charge?
(a) a sodium atom with 11 protons, 11 electrons, and 12 neutrons (b) a calcium atom with 20 protons, 18 electrons, and 20 neutrons (c) a helium atom with 2 protons, 2 electrons, and 2 neutrons (d) an iron atom with 26 protons, 26 electrons, and 30 neutrons
What does an atom of 2 protons 2 neutrons and 2 electrons make?
If the atom has a balanced electrical charge, then # of protons = # of electrons, so the atom has 2 protons (Helium). The vast majority of Helium atoms have 2 neutrons.
What element has 2 electrons (neutral atom )?
Helium has 2 protons, 2 neutrons, and 2 electrons.
How many protons and neutrons and electrons has helium got?
Helium has 2 protons, 2 neutrons, and 2 electrons. The atomic number of helium is 2, which indicates it has 2 protons and 2 electrons in a neutral atom.
How many of each of the elementary particles are contained in the helium atom?
A helium atom consists of 2 protons, 2 electrons and 2 neutrons.
Neutral atom with 53 protons in its nucleus would have how many electrons orbiting the nucleus?
For a standard atom, the number of protons, electrons, and neutrons is the same. For example: 2 Protons - 2 Neutrons - 2 Electrons Helium 3 Protons - 3 Neutrons - 3 Electrons Lithium 4 Protons - 4 Neutrons - 4 Electrons Beryllium So... 53 Protons - 53 Neutrons - 53 Electrons Iodine
which atom has 2 protons 2 electrons 2 neutrons?
Helium isotope
How may electrons neutrons protons are found in the helium?
In normal Helium(He) atom there are 2 electrons, 2protons and 2 neutrons.
How many protons and nuetrons are in helium?
The normal helium atom has two protons and two neutrons in the nucleus, and two electrons in the "shell".
How many protons and electrons does the element Helium have?
One atom of helium contains 2 protons and 2 electrons. The most abundant isotope of helium, helium-4, has 2 neutrons. The other, rare isotope of helium, helium-3, has 1 neutron. (Source: Wikipedia)
