∙ 11y agoThe description given is not of an atom, which must be electrically neutral, but rather of an ion, specifically a lithium-6 monovalent cation: Any atom or ion with 3 protons is lithium, and the mass number 6 is obtained by adding together the numbers of protons and neutrons. This is an ion formed from the less common of the two naturally occurring isotopes of lithium, those with mass numbers 6 and 7.

A neutral atom contains 5 neutrons and 4 protons how many electrins does it contain?
Protons: 5 Neutrons: 7 Electrons: 5
What is the difference between an oxygen 16 atom and an oxygen 18 atom?
In the nucleus of an oxygen-18 atom there are 10 neutrons while in the nucleus of an oxygen-16 atom there are only 8 neutrons. The number of electrons and protons always stay the same.
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 has 2 electrons 2 neutrons and 2 protons?
An atom with 2 protons is naturally Helium. Therefore, this isotope would be called helium - 5 because it has 5 particles in its nucleus, 2 protons and 3 neutrons.
How may electrons neutrons protons are foundin the helium atom?
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
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.
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
What element has 2 electrons (neutral atom )?
Helium has 2 protons, 2 neutrons, and 2 electrons.
How may electrons neutrons protons are found in the helium?
In normal Helium(He) atom there are 2 electrons, 2protons and 2 neutrons.
which atom has 2 protons 2 electrons 2 neutrons?
Helium isotope
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)
How many protons and neutrons are in an a-particle?
2 protons and 2 neutrons (an a-particle is effectively a helium atom without any electrons).
If helium has 2 protons 2 electrons it is considered what?
If it has 2 protons 2 electrons and 2 neutrons then it's your normal neutral Helium atom.
What atom do you build with 2 protons 2 neutrons and 2 electrons?
Helium-4 has 2 protons and 2 neutrons, and is formed both by the fusion of hydrogen in stars and in the decay of heavy radioactive elements. The neutral atom has 2 electrons.
