What element has 3 protons, 4 neutrons and 4 electrons?
Since the identity of an element is determined solely by the number of protons in an atom of that element, and this atom has three protons, the element is that with an atomic number of 3, or lithium.
However, we can go into more detail with the information you have. Since there are a total of 3+4=7 nucleons, the mass of the atom is 7. Also, since it has one more electron than it does protons, it has a net -1 charge. So the symbol for this ion would be 7Li- (where the 7 and – are both superscripts).
An atom with 3 protons and 4 neutrons will have a valency of – 3 protons = 3 electrons The electronic configuration is 2, 1 Hence, the valency is 1. Therefore option (c) is correct. (c) Given that, number of protons in an atom = 3 and number of neutrons = 4 K L Electronic configuration of 3Li = 2, 1 As, it has one valence electron, therefore its valency is also 1.Each element has a unique atomic number. The atomic mass on the other hand is the number of protons plus the number of neutrons (so, essentially, it is the mass of the nucleus).Find your element on the periodic table. The table orders elements by atomic number and separates them into three main groups: metals, non-metals You need the atomic number to find the amount of protons and/or electrons, unless you have the amount of neutrons and the atomic mass, in which…
What element has 53 protons and 74 neutrons? – eNotes.com – Neutron: They are neutral subatomic particles found in the center of the nucleus. They were discovered by James Chadwick in 1932. Finding Protons, Neutrons, and Electrons of Isotopes. Isotopes are atoms of the same element with the same proton number, but different number of…Most hydrogen atoms have no neutrons but the deuterium isotope (H-2) has 1 neutron and the tritium isotope (H-3) has 2 neutrons.. How many neutrons are in an element? For hydrogen, the atomic mass is 1 because there is one proton and no neutrons.answer choices. neutrons. electrons. protons. Q. If an atom has 24 protons and 24 electrons, what is the atomic number of this element? answer choices.
How to Find the Number of Protons, Neutrons, and Electrons – Three main particles form every atom. Protons and neutrons cluster in the nucleus at the center of the atom. Electrons form a spinning cloud around the Isotopes occur when atoms of the same element have different masses. Since the number of protons of an element doesn't change, the difference in…Transcribed Image Text from this Question. PARTII fundamentals 1) An element has 3 protons and 4 neutrons in its nucleus. What is the notation to identify this element ? The 2) If the atomic number of a neutral element is 35 and contains 40 neutrons. what is the element and its notation?All atoms of the same element have the same number of protons, but some may have different numbers of neutrons. What is the atomic number and the mass number of an isotope of lithium containing 4 neutrons? Solution. A lithium atom contains 3 protons in its nucleus irrespective of the…
