What element has 3 electrons 3 protons and 4 neutrons?
lithium
A lithium atom contains 3 protons in its nucleus. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always Z = 3. The mass number, however, is A = 6 for the isotope with 3 neutrons, and A = 7 for the isotope with 4 neutrons.
What is the mass of an atom with 3 protons 4 neutrons and 3 electrons?
Stylized lithium-7 atom: 3 protons, 4 neutrons, and 3 electrons (total electrons are ~1⁄4300th of the mass of the nucleus). It has a mass of 7.016 Da. Rare lithium-6 (mass of 6.015 Da) has only 3 neutrons, reducing the atomic weight (average) of lithium to 6.941.
Which element has 4 neutrons 3 electrons and 4 protons?
The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons.
Which atom has 3 protons 3 neutrons and 3 electrons?
lithium atom
A lithium atom contains 3 protons in its nucleus irrespective of the number of neutrons or electrons. a. b. Notice that because the lithium atom always has 3 protons, the atomic number for lithium is always 3.
What isotope has 3 protons and 3 electrons?
Lithium-7. Lithium-7 is by far the most abundant isotope of lithium, making up between 92.2% and 98.1% of all terrestrial lithium. A lithium-7 atom contains three protons, four neutrons, and three electrons.

What is the charge of an atom with 4 protons and 4 electrons?
The atomic mass is expressed by the number of massive particles, protons, and neutrons, and since we have 5 neutrons, the isotope is 9Be . Finally we can assign the charge. There are 4 protonic charges, and 4 electronic charges: the isotope is neutral.
Which atom has 3 protons 4 neutrons and 2 electrons?
The atomic number of Lithium (Li) is 3. Hence, X for the given atom is Li. As the given atom contains one extra proton compared to the electrons, therefore, the charge on the atom is +1.
What is an atom with 4 protons 5 neutrons and 4 electrons?
4 protons, 5 neutrons, and 4 electrons are there in an atom of beryllium.
What element has 3 protons?
Answer and Explanation: The element lithium has three protons. It has the chemical symbol Li, and it exists as two isotopes, with three and four neutrons. It is a soft,… See full answer below.
What are 3 differences between protons and electrons?
Key Differences Between Electron and Proton An electron is a negatively charged component of an atom whereas the proton is a positively charged body. The electrons are present outside the nucleus in the orbiting shells. Electrons are highly mobile as these are present in the shells of the atoms and can be easily freed on supplying energy.
How many protons are in a neutron?
They all have six protons, but different numbers of neutrons, as seen in a model of 12C and 13C, below. Neutrons are also in the nucleus. A neutron has a mass similar to a proton, but has no charge. Compared to protons and neutrons, the mass of an electron is very small.
How do you calculate the number of protons and neutrons?
The number of neutrons can be calculated by subtracting the number of protons from the atomic mass, which is 16 minus eight for oxygen.An atom is primarily comprised of neutrons, electrons and protons. The neutrons and protons are contained within the nucleus, a tight central area of the atom.
