What atomic particle has two protons and two neutrons?
Any atom with two protons has an atomic number of two and is an isotope of helium. With two neutrons, there are a total of nucleons is four, so the isotope or mass number is four (sum of protons plus neutrons). Therefore the atom is helium-4 or 4He, which is stable (not radioactive) and the most common isotope of helium in nature, account for nearly 100% of all helium.
What is the total number of neutrons in an atom of 7 lithium 3?
There are 4 neutrons in a lithium-7 atom. Lithium, which has atomic number 3, has 3 protons in its nucleus. If its atomic number is 3 (which is the number of protons in its nucleus) and its mass number is 7, we can find the number of neutrons by subtracting the atomic number from the mass number. In this case, 7 minus 3 equals 4.
What element has four protons four electrons and five neutrons?
There are too many electrons. This would be a negative ion of lithium-6 (stable but less common isotope) that does not occur naturally. The element with 3 electrons, 3 protons, and *4 neutrons* is lithium-7, the most common isotope. It forms a stable positive ion (2 electrons).
What am I have 4 neutrons and I am metallic what am I?
7Li or lithium-7.The mass number of an isotope is the sum of the protons and neutrons in its atomic nuclei. The atomic number of Li is 3, so lithium-7 would have 3 protons and four neutrons.
How many electrons protons and neutrons are in beryllium?
One beryllium atom has four (4) electrons, four (4) protons, and three (3), five (5) or six (6) neutrons, depending on the isotope being considered. The only stable isotope is Beryllium-9 (with 5 neutrons) but beryllium-10 (with 6 neutrons) has a relatively long half-life of 1.51 million years.

What is the number of protons electrons and neutrons in sulfur?
The number of electrons and protons in a neutral sulfur atom is the same as the atomic number of sulfur, which is 16. However, the number of neutrons can vary: Four isotopes of sulfur occur naturally, with 16, 17, 18, and 20 neutrons. Some 95 % of the atoms in a typical sample have 16 neutrons per atom.
How many protons neutrons and electrons are in atom of strontium?
38There can be multiple atoms that have the same number of neutrons, these are called isotopes. The most common isotope of strontium (one of four stable isotopes), is strontium 88. This means that the number of protons and neutrons together in that isotope is 88. And since all atoms of strontium (regardless of their isotope) have 38 protons, that means that the most common isotope of strontium has 50 neutrons.
What is the total number of neutrons in an atom of 7 lithium 3?
There are 4 neutrons in a lithium-7 atom. Lithium, which has atomic number 3, has 3 protons in its nucleus. If its atomic number is 3 (which is the number of protons in its nucleus) and its mass number is 7, we can find the number of neutrons by subtracting the atomic number from the mass number.

How many protons and neutrons and electrons does lithium have?
how many protons neutrons and electrons does lithium have? 3 protons 4 neutrons 3 electronsA lithium atom has three protons and so three electrons. The number of neutrons depends on the isotope, with the two naturally occurring stable isotopes of lithium, 6Li and 7Li, having 3 and 4 neutrons respectively.3: In any neutral atom, there are the same number of electrons as of protons, and the number of protons is the same as the atomic number, which for lithium is 3.
How many protons neutrons electrons in the nucleus of chlorine?
Chlorine atom has 17 protons and 17 electrons. The number of neutrons depends on the isotope considered. Chlorine has four isotopes: Cl-35, Cl-36, Cl-37 and Cl-38 with 18, 19, 20 and 21 neutrons respectively. However out of these, Cl-35 and Cl-37 are the most stable isotopes.
What am I have 4 neutrons and I am metallic what am I?
7Li or lithium-7.The mass number of an isotope is the sum of the protons and neutrons in its atomic nuclei. The atomic number of Li is 3, so lithium-7 would have 3 protons and four neutrons.
How many electrons protons and neutrons are in beryllium?
One beryllium atom has four (4) electrons, four (4) protons, and three (3), five (5) or six (6) neutrons, depending on the isotope being considered. The only stable isotope is Beryllium-9 (with 5 neutrons) but beryllium-10 (with 6 neutrons) has a relatively long half-life of 1.51 million years.
What kind of atom has four of each kind of proton electron and notron?
The isotope berrylium-8 has four each of protons, electrons, and neutrons.
If an atom has six protons and four neutrons what is its?
It's an isotope of Carbon, specifically Carbon-4. An atom in its neutral state will have equal numbers of protons and neutrons. The number of protons is also called the atomic number, and makes the specific atom what it is. (Carbon always has 6 protons, 5 protons is Boron and 7 protons is Nitrogen.) If there is an unequal number of neutrons, it usually indicates an isotope, an atom that isn't in the natural, most commonly occurring ground state. In this instance, it is Carbon-4. (Carbon-4, also called C-4 is a common explosive because of it's unstable nature.)
Calculate the number of protons electrons and neutrons in helium-6?
Helium-6 has two protons and electrons and four neutrons.
