Your answer is B and the element is Carbon
So what your looking for is matching isotopes. Isotopes are elements that are the same in amount of protons but different in mass meaning different number in neutrons. Because when you add the total protons and neutrons together you get your atomic mass. So this can be written as X=said element, top number above=different atomic mass, bottom number below=atomic number. Hope this help!!
Be careful because answer A has same masses but different atomic numbers so different atoms(elements)!!!
Answer:atoms contain small negatively charged particles that are called electrons
Explanation:
Answer:
A
Explanation:
a is the right answer abi
Answer : The correct option is, electrons are not shared equally between atoms.
Explanation :
Polar covalent bond : It is a type of chemical bond in which a pair of electrons are not shared equally between the two atoms.
In polar covalent bond, the electrons are not shared equally because one atom spends more time with the electrons than the another atom. In this, one atom has more tendency to pull an electron than the other atom.
For example : 
is an example of polar covalent bond. In water molecule, oxygen spends more time with the electron than the hydrogen and oxygen carries a partial negative charge.
Crystallization is the process of atoms forming a material with a crystal structure
