What do you call an atom with 2 protons 2 neutrons and 2 electrons?
A typical helium atom contains 2 protons, 2 neutrons, and 2 electrons.
What is the charge of 2 protons 2 neutrons 2 electrons?
2p++ 2e− = 0 . Therefore, a helium atom with two electrons, two protons, and two neutrons has no charge.
What particle is made up of 2 protons and 2 neutrons?
Alpha particles
Alpha particles (a) are composite particles consisting of two protons and two neutrons tightly bound together (Figure 1). They are emitted from the nucleus of some radionuclides during a form of radioactive decay, called alpha-decay.

What is the charge of an atom with 2 protons and 1 electron?
As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged. The negative charge of one electron balances the positive charge of one proton….2.1 Electrons, Protons, Neutrons, and Atoms.

What particle is composed of a proton and neutron?
Quarks
Quarks make up protons and neutrons, which, in turn, make up an atom’s nucleus. Each proton and each neutron contains three quarks. A quark is a fast-moving point of energy.
Why do alpha particles have 2 protons?
α Particles have a positive charge and are identical with helium nuclei, and consist of two protons and two neutrons. Because of their double-positive charge, α particles have great ionizing power, but their large mass results in very little penetration.
What is an atom with 2 protons and 4 neutrons?
Answer: Consider the element helium. Its atomic number is 2, so it has two protons in its nucleus. Its nucleus also contains two neutrons. Since 2 + 2 = 4, we know that the mass number of the helium atom is 4.
What is the atom with 2 neutrons and 1 proton?
Tritium
Tritium is a hydrogen isotope consisting of one proton, two neutrons and one electron. It is radioactive, with a half-life of 12.32 years.
2.1 Electrons, Protons, Neutrons, and Atoms. All other elements have neutrons as well as protons in their nucleus, such as helium, which is depicted in Figure 2.2. The positively charged protons tend to repel each other, and the neutrons help to hold the nucleus together. The number of protons is the atomic number,…
Which is the simplest atom with one proton and one neutron?
Both protons and neutrons have a mass of 1, while electrons have almost no mass. The element hydrogen has the simplest atoms, each with just one proton and one electron.
What are the three particles that make up an atom?
2.1 Electrons, Protons, Neutrons, and Atoms All matter, including mineral crystals, is made up of atoms, and all atoms are made up of three main particles: protons, neutrons, and electrons. As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged.
How are protons and electrons different from each other?
As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged. The −1 charge of one electron balances the +1 charge of one proton. Both protons and neutrons have a mass of 1, while electrons have almost no mass.
