It is hydrogen element. It is tritium isotope of hydrogen.
There is no such element: an element is neutral, so it has equal numbers of protons and electrons.Impossible:2 protons 4 neutrons and 3 electrons is the IMpossible He-1 isotope with mass number 6 (=2p+4n). Helium does not accept electrons because it is noble.Possible:2 protons 4 neutrons and 2 electrons is (elemental) Helium, isotope with mass number 6 (=2p+4n)3 protons 4 neutrons and 3 electrons is (elemental) Lithium
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
Manganese: 25 protons, 30 neutrons, 25 electrons. Magnesium: 12 protons, 12 neutrons, 12 electrons. Argon: 18 protons, 22 neutrons, 18 electrons. Potassium: 19 protons, 20 neutrons, 19 electrons. Gold: 79 protons, 118 neutrons, 79 electrons. Hydrogen: 1 proton, 0 neutrons, 1 electron. Fluorine: 9 protons, 10 neutrons, 9 electrons. Silicon: 14 protons, 14 neutrons, 14 electrons. Boron: 5 protons, 6 neutrons, 5 electrons. Bromine: 35 protons, 45 neutrons, 35 electrons.
Atoms are the basic constituents of matter. Protons, Neutrons, And Electrons are the main partilces. Electrons orbit outside nucleus. Protons and neutrons reside in the nucleus.

An element must always have the same number of protons as it's atomic number. The number of electrons may vary, making an atom into an ion, and the number of neutrons can also vary which is why we have different isotopes of the same element.
No, an element is 1 atom with a certain number of protons, neutrons, and electrons.
The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.
Atoms are made up of three types of particles: protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons determines the element of the atom, while the number of neutrons and electrons can vary.

Helium has 2 protons and 2 electrons. He-3 and He-4 isotopes have 1 and 2 neutrons.
Protons: 2 neutrons: 2 electrons: 2 Helium-3: 2 protons, 1 neutron, 2 electrons Helium-4: 2 protons, 2 neutrons, 2 electrons
Atoms are the basic constituents of matter. Protons, Neutrons, And Electrons are the main partilces. Electrons orbit outside nucleus. Protons and neutrons reside in the nucleus.
In neutral atoms (with the same number of protons and electrons), the number of protons and electrons equal the atomic number. If our atom has 9 electrons, is neutral, and therefore has 9 protons, it is element #9: Flourine, which has an atomic mass of 19: 9 protons plus 10 neutrons.
