<h2>Atoms whose atomic number are the same but whose mass numbers are different are called : Isotopes </h2>
Explanation:
Isotopes
They are the elements with same atomic number but different mass number .
for example : Protium , deuterium and tritium are isotopes of hydrogen .
: C-14 and C-12 are isotopes of oxygen .
: Cl-35.5 and Cl-37 are isotopes of chlorine
Alpha particles
They are helium nuclei with +2 unit charge and 4 a.m.u mass
They are represented as : He₂⁴.
Ions
The atom carrying charge is called as ion .
It can be of two types : Cation and anion
cation :atom with positive charge
Anion : atom with negative charge
Beta particles
They are actually particles with charge and mass of electron and is represented as :₀ e⁻¹
Answer:
The flow of photsynthesis comes from the sun
Explanation:
in which the plant absorbs. The plant then turns it into a type of food like glucose, protein, vitamin c etc. the plant uses this energy to help it grow!
Hoped this helped :)
The writers of the Articles of Confederation wanted to preserve the states' sovereignty.
Answer:
<u><em>(B.) a significantly lower mass that protons</em></u>
Explanation:
The mass (in g) of an electron is 9.11 ×
g, which is significantly lower than the mass of protons and neutrons which are approximately the same. They are extremely small (equal to 0 amu), contributing nothing to the overall mass of the atom.
The nucleus has a mass of 1 amu and is positively charged.
Depending on what you are doing, virtual, or in school, you can contact your school and you ask them, or you can have your teacher, based on the subject, tutor you.
