What element has 4 protons 5 neutrons and 2 electrons? How many protons does nihonium have? What is the name of a proton acceptor in a reaction? How many protons does berkelium have? Calculate the net charge on a substance consisting of a combination of 7.0x10^13 protons and 4.4x10^13 ...
A variation of an element, has different number of neutrons, but same number of protons and electrons, is called what? What does an atom consist of? Which subparticle component of an atom can be changed but it still remains to be the same element? I. Electron II. ...
Everyone learns about Helium in school. It is the second element in the periodic table having 2 protons, 2 neutrons and 2 electrons - having anatomic mass of 4. But another form of Helium has been in the news lately and it is called Helium-3. Helium-3, also written as3He, is a lig...
Alpha Particles A helium nucleus Contains: 2 protons 2 neutrons Notation: He 4 2 Alpha Particles Move at about 1/10 th the speed of light. Can be stopped by: aluminum foil sheet of paper skin Beta Particles A fast moving electron (negatively charged particle) formed by decomposition of a ...
Alpha decay in an element causes it to change into a lighter element. Beta decay occurs when a nucleus has too many neutrons for its number of protons. In this process, a neutron, which is electrically neutral, spontaneously changes into a positively charged proton by emitting a negatively ...
If you look inside an atom, you find tiny particles called protons, neutrons, and electrons. Atoms of each element have different numbers of these particles. Protons and electrons have electrical charges. You can think of this as being similar to a battery, which has a + (positive) and -...
© Boardworks Ltd 2007 1 of 44 What is the atomic number? Every element has a unique atomic number. This is the number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the ...
Furthermore, an atom is the smallest particle of an element. Most noteworthy, Atom is made up of three particles namely neutron, proton, and electron. All these elements have different properties, size, and mass. Let us discuss these elements in brief. What is Neutron? Neutron is the ...
Charge is determined by the ratio of the subatomic particles protons and electrons. Electrons are negatively charged and protons are positively charged so if one particle is more than the other the entity becomes charged. Answer and Explanation:1 ...
Deuterium is one of only five stable nuclides that has an odd number of both protons and neutrons. In most atoms, odd numbers of protons and neutrons are unstable with respect to beta decay. The presence of deuterium has been confirmed on other planets in the solar system and in the spectr...
