What is the same number of two particles in an atom? An atom usually contains an equal number of positively charged protons and negatively charged electrons. This makes the atom itself electrically neutral. What has the same number in an atom?...
Which subatomic particle has a negative charge? A third type of subatomic particle, electrons, move around the nucleus. The electrons have a negative electrical charge. An atom usually contains an equal number of positively charged protons and negatively charged electrons. What...
What is a subatomic particle with a positive charge that is in the nucleus of an atom Quizizz? Protons are positively charged and the lightest subatomic particle. Neutrons have no charge and are the lightest subatomic particle. Which subatomic particle has...
Why are subatomic particles neutral? Neutron is electrically neutral and proton is positively charged and an electron is negatively charged. In an atom, the number of protons is equal to the number of electrons. Hence, the overall charge in an atom...
What 2 subatomic particles have the same mass? Answer and Explanation: The two subatomic particles that have the same mass are protons and neutrons. Neutrons and protons each have an atomic mass of about one atomic mass unit (amu). Which subatomic...
What subatomic particle is electrically charged? There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have...
What are the 3 subatomic particles present in an atom? A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). What subatomic particles do? Subatomic particles play two vital roles in the...
How can an electron move to another energy level? An atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a...
What determines distance between energy levels? The energy levels in an atom are similar to the rungs of a ladder, but they get closer together as they get farther from the nucleus. For an electron to move from one energy level...
How many electrons can the 2nd and 3rd energy levels hold? Answer and Explanation: The number of electrons that the second level can hold is up to eight electrons (2+6). The first level/ shell can hold up to two (2). The...
