In most atoms, electrons occupy a zone exterior to the nucleus.
Answer:
.24 mg
Explanation:
The mineral contains .016 % silicon
mass of the mineral = 1.5 kg
mass of silicon = 1.5 x .016 %
= 1.5 x .016 / 100
= 24 x 10⁻⁵ kg
= 24 x 10⁻² mg
= .24 mg .
<span>An ionic bond is the transfer of electrons and a covalent bond is a sharing of electrons
Happy studying! ^_^</span>
That looks like helium
since it has 2 protrons, neutrons, and electrons.
Answer:
The charge of nucleus will be +2.
Explanation:
Given that,
Proton = 16
Neutron = 14
electron = 18
We know that,
Atomic number :
The number of proton in the nucleus is equal to the atomic number.
The number of protons is equal to the number of electrons for neutral atom.
So, the atomic number is same as the number of electrons.
Here, the number of electron is more than 2 of number of proton.
Hence, The charge of nucleus will be +2.
