Explanation please: + Atoms are mostly ___ ___. empty space There is a ___, ___, ___ charged area at the center of the atom – called the ___. small dense positively nucleus The positive alpha particles were ___ by the nucleus if they got close enough…and thus we have the ...
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. When people draw ...
What are the fundamental particles?Question:What are the fundamental particles?Atoms:An atom is the smallest unit that composes matter. These are combined to form molecules or compounds. Atom was discovered by John Dalton in 1804Answer and Explanation: Become...
Neutrons are subatomic particles, with a neutral charge and slightly more mass than protons, found in the nucleus of everyatomexcept hydrogen. When not confined in a nucleus, they are known as “free” neutrons and are generated by nuclear fission and fusion. Neutrons have significant applications...
Protons are the positively charged subatomic particles in the atom. They are located with the neutrons, the neutrally charged particles, in the nucleus of the atom. The third type of subatomic particle that helps to form atoms is the electron. These are negatively charged and are found o...
Atoms:Atoms are the smallest indivisible working unit of matter. It is composed of three subatomic particles: neutrons, electrons, and protons. Neutrons are neutrally charged whereas electrons are negatively charged. Protons are the subatomic particles of an atom that are positively charged....
Since an atom in the ground state has the same number of protons as it does electrons, atoms are electrically neutral unless ionized (i.e., their electron number changes). An atom's proton number is its atomic number on the periodic table and determines the identity (name) of the element...
TODAY’S BIG QUESTION! ARE ALL ATOMS THE SAME? Atomic Structure Are atoms all the same? Are atoms all the same? There are 92 types of atom in the universe. Are atoms all the same? There are 92 types of atom in the universe. Everything is made up of one or more of these 92 type...
And when they collide with the atoms in Earth’s atmosphere, they break up into smaller particles—muons. 而当它们和地球大气里的原子撞击的时候,就会分裂成更小的粒子——介子。 Now, these muons are still highly energized, so they can easily pass on down to the Earth’s surface. ...
Atoms: Atoms are the purest form of matter. They consist of protons, neutrons, and electrons. The periodic table lists all of the different types of atoms that are known to exist and are known as elements. Answer and Explanation: An atom that has more protons than electrons is called a ...
