<u>Answer:</u>

7

<u>Explanation</u>:

An isotope is an atom that has a different number of neutrons than the standard for that atom.

1)<em>Nitogen</em><em> </em><em>-</em><em>1</em><em>4</em><em> </em><em>has</em><em> </em><em>7</em><em> </em><em>protons</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>nucleus</em><em> </em><em>for</em><em> </em><em>its</em><em> </em><em>an</em><em> </em><em>isotope </em><em>of</em><em> </em><em>nitrogen </em><em>which</em><em> </em><em>has</em><em> </em><em>an</em><em> </em><em>atomic</em><em> </em><em>number</em><em> </em><em>o</em><em>f</em><em> </em><em>7</em><em>.</em>

<em>2</em><em>)</em><em>Now</em><em> </em><em>we</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>number</em><em> </em><em>of </em><em>neutrons</em><em>.</em><em> </em><em>This</em><em> </em><em>is</em><em> </em><em>implied</em><em> </em><em>in</em><em> </em><em>the</em><em> </em><em>name</em><em> </em><em>of </em><em>the</em><em> </em><em>isotope</em><em> </em><em>whereby</em><em> </em><em>the</em><em> </em><em>protons</em><em> </em><em>and</em><em> </em><em>neutrons</em><em> </em><em>add</em><em> </em><em>up</em><em> </em><em>to</em><em> </em><em>its</em><em> </em><em>atomic</em><em> </em><em>number.</em><em> </em><em>So</em>

<em>(</em><em>1</em><em>4</em><em>-</em><em>7</em><em> </em><em>protons</em><em>=</em><em> </em><em>7</em><em> </em><em>neutrons</em><em>.</em><em>)</em>

So it has 7 neutrons.

Prform the following operation and express the answer in scientific notation 6.0 x 10^3-2.310^3
Marrrta [24]

The value 6.0 x 10^3- 2.3 × 10^3 in scientific notation is 3.7 × 10^3.

<h3> What is scientific notation?</h3>

Scientific notation is a way to write very large or very small numbers so that they are easier to read and work with.

You express a number as the product of a number greater than or equal to 1 but less than 10 and an integral power of 10 .

<h3>Why it is used? </h3>

There are two reasons to use scientific notation.

  • The first is to reveal honest uncertainty in experimental measurements.
  • The second is to express very large or very small numbers so they are easier to read.

Given,

= 6.0 x 10^3- 2.3 × 10^3

= (6.0 - 2.3) × 10^3

= 3.7 × 10^3

Thus, we find that the value 6.0 x 10^3- 2.3 × 10^3 in scientific notation is 3.7 × 10^3.

Last question<br> help<br> im confusion
Andrej [43]

Remark

The given thing on the right is a positron. The mass for these subatomic particles is considered to be 0. It's atomic number is 1 which means it is a blood relative of a proton.

So essentially what happens is that X is one space to the left on the periodic table. But let's solve this a little bit more formally.

Solution

_{65}^{147}\text{Tb}\longrightarrow _{z}^{y}\text{x} +_{1}^{0}{e}

y stays the same at 147. It is z that changes.

65 = z + 1     Subtract 1 from both sides.

64 = z

So the chemical with 64 as its position on the periodic table is
