A covalent compound<span> is made when two or more nonmetal atoms </span>bond<span> by sharing valence electrons. The shared valence electrons between two nonmetal atoms is</span>called<span> a </span>covalent bond<span>. </span>Covalent bonds<span> are </span>formed<span> when two atoms begin sharing electrons.</span>
The kinetic energy of its molecules has decreased<span>

Why do you want someone to do your entire asighnment for you
The answer is <span>The number with a higher value is the mass, and the number with a lower value is the number of protons.
The number with a higher value is the mass. This is because t</span>he mass number of the element is the sum of the number of protons and number of neutrons in the nucleus of the atom. On the other hand, the number with a lower value is the number of protons. The number of proton in the nucleus of the atom is t<span>he atomic number of the element. It involves only numbers of protons, thus, it has the lower value than the mass number.
For example, hydrogen has 1 proton and 1 neutron. Its atomic number is 1 (= number of protons). Its mass number is 2 (1 proton + 1 neutron = 2). Thus, mass number has higher value than the atomic number.</span>
Protons can't change in stable elements so its means that is Barium
