No. All atoms of a given element are alike in the number of protons, which is the atomic number of an element. However, the number of neutrons in the nucleus can vary. Atoms of elements with the same number of protons but different numbers of neutrons are called isotopes. All atoms of a given element in their ground state have the same number of electrons as they do protons, but if they form ions, the number of electrons will increase or decrease, depending on the element, but the number of protons remains the same.
Elements in each group on the periodic table have similar properties due to their similar electron configurations. These properties include similar reactivity, chemical behavior, and physical characteristics. This allows for elements within the same group to be grouped together based on their shared properties and patterns.
Alpha particles are emitted by heavy elements like uranium and radium. Beta particles are emitted by elements like strontium and tritium. Gamma rays are emitted by radioactive decay of unstable nuclei across all elements.
All elements, including iron, exist when pure in an electrically neutral state. This does not mean that the elements can not contain charged particles, but rather that the number of total negatively and total positively charged particles must be the same in a pure element.
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
A sample of water molecules is an example of a matter where all the particles (H2O molecules) are identical. Each water molecule consists of two hydrogen atoms and one oxygen atom, making them indistinguishable from one another.
neutrons of all atoms are alike
They are all Elements and They are diiferent substances
they all take up space and all have matter, mass, and weight
Alike. They are both atomic particles with a positive charge.
yes
Compound are all alike because they all have two elements combined together like iron+sulfide=ironsulfide
Compound are all alike because they all have two elements combined together like iron+sulfide=ironsulfide
they all share the smae elements
pure substance
true
All chemical elements are formed from protons, neutrons (excepting H-1) and electrons.
tv because no elements are true
