An atom contains 16 protons, 18 neutrons, and 16 electrons what is its mass number?
Name the element of which this is an isotope.
Answers
16

Right from the start, you know that you're indeed dealing with a neutral atom, since the number of protons it has in its nucleus is equal to the number of electrons it has surrounding its nucleus.
Now, an atom's atomic number,
Z
, tells you how many protons it has in its nucleus. Nothing more, nothing less.
In your case, you are told that the atom contains
16
protons in its nucleus, which means that
Z
will be equal to
Z
=
16
A quick look in the periodic table will reveal that you're dealing with an atom of sulfur,
S

An atom's mass number,
A
, tells you how many protons and neutrons it contains in its nucleus. Since the number of protons is given by
Z
, you can say that

In your case, the atom contains
18
neutrons in its nucleus. This means that
A
will be equal to

+
18
=

Finally, focus on the atom's electron configuration, which you know that must account for a total of

Answers
Answer:
The answer is 3.0 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 15 g
volume = 5 mL

Explanation:
im the best rust player so ofc i know
The smallest packet of electromagnetic energy that can be absorbed or emitted is photon.
What is electromagnetic energy?Radiation that travels in waves and has both electric and magnetic fields. It is derived from both natural and artificial sources. The power of electromagnetic energy can range from low to high.
Proton and electron are particles not any form of energy.Wave is a form of radiation.Photon is a small packets of energy whose energy is equal to hυ.Hence photon is the smallest packet of electromagnetic energy.

How many electrons, protons, and neutrons are contained in each atom?
a. 132/55 Cs
b. 59/27 Co
c. 163/69 Tm
d. 70/30 Zn
Answers
The second is atomic number, this is the number of protons-this number will never vary or change within that element because the number of protons is what makes an element that element
So to find the number of neutrons, you subtract the second number from the first.
The number of electrons is the same as the number of protons unless there is an additional charge which none of these have
A) neutrons: 132-55=77 neutrons
Protons:55
Electrons: 55
B)n: 59-27=32

How are u supposed to tell how many neutrons and electrons an element has?? Pls help if u know the answer.
Answers
Answer:
Explanation:
The atomic number (number at the top) is the amount of protons and the amount of electrons. So if an element has an atomic number of 5, you know that it has 5 protons and 5 electrons. The atomic mass (number at the bottom) is the amount of protons and neutrons added together.
Why are black holes so difficult to detect?
Answers
Answer:
Black holes are so dense that light cannot escape from them, and they are difficult to detect. Satellites above the Earth's atmosphere can detect bursts of high energy radiation given off by black holes.

A fluoride ion (F) has the same electron configuration as
A. Na+
B.Na
C.Cl-
D.Cl
Answers
Answer:
Option A. Na⁺
Explanation:
Floride ion (F¯) simply indicates that the fluorine atom has gain an extra electron.
Thus, the electronic configuration of the fluoride ion (F¯) can be written as follow:
F¯ (10) => 1s² 2s²2p⁶
Next, we shall determine the electronic configuration of the element given in options to see which is the same as that of the fluoride ion (F¯). This is illustrated below:
Na⁺ (10) => 1s² 2s²2p⁶
Na (11) => 1s² 2s²2p⁶ 3s¹
Cl (17) => 1s² 2s²2p⁶ 3s²3p⁵
Cl¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶
From the above illustrations, we can see that the fluoride ion (F¯) has the same electronic configuration as Na⁺.
Each element is made up of electrons and these electrons are filled in different shells. These are the following shells in the electrons:
K shellL shellM shellN shellAccording to the question, the fluoride ion has 10 electrons in its 2 shells, that is 2 in K shell and 8 in L shell.
A similar number of shell and electrons to the fluoride ion is sodium ion ([tex]Na^{+}[/tex])
The [tex]Na^+[/tex]has a total 10 number of electrons, hence the electronic configuration is 2 and 8.
Therefore, the [tex]Na^+[/tex] is the correct option.
