import com.google.android.gms.ads.interstitial.InterstitialAd
import com.google.android.gms.ads.interstitial.InterstitialAdLoadCallback

class MainActivity : AppCompatActivity() {

    private var mInterstitialAd: InterstitialAd? = null


    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val one_Page: TextView = findViewById(R.id.one_Page)

        one_Page.setOnClickListener {
            val intent = Intent(this, PageActivity2::class.java)
            // start your next activity
            startActivity(intent)

        }

I think maybe you are missing a few steps to get it right, to do that please follow these steps:

Note: I will use sample ids to load demo ads, you need to make sure it's worked then think about replacing the sample ids with real ids

1: Setup Admob dependencies:

implementation 'com.google.android.gms:play-services-ads:20.1.0'

2: Add snippet code to your AndroidManifest.xml inside the <application> tag

<!-- Sample AdMob app ID: ca-app-pub-3940256099942544~3347511713 -->
<!-- Replace sample id if you have a real id from AdMob project - pattern ca-app-pub-xxxxxxxxxxxxxxxx~yyyyyyyyyy --> 
<meta-data
     android:name="com.google.android.gms.ads.APPLICATION_ID"
     android:value="ca-app-pub-3940256099942544~3347511713"/>

3: Initialize Admob and load an ad:

import com.google.android.gms.ads.interstitial.InterstitialAd
import com.google.android.gms.ads.interstitial.InterstitialAdLoadCallback
class MainActivity : AppCompatActivity() {
  private var mInterstitialAd: InterstitialAd? = null
  private final var TAG = 'MainActivity'
    override fun onCreate(savedInstanceState: Bundle?) {
      super.onCreate(savedInstanceState)
      setContentView(R.layout.activity_main)

      // Initialize Admob
      MobileAds.initialize(this) {}
      var adRequest = AdRequest.Builder().build()
      // ca-app-pub-3940256099942544/1033173712 is a sample interstial id. 
      InterstitialAd.load(this,"ca-app-pub-3940256099942544/1033173712", adRequest, object : InterstitialAdLoadCallback() {
        override fun onAdFailedToLoad(adError: LoadAdError) {
          Log.d(TAG, adError?.message)
          mInterstitialAd = null
        }

        override fun onAdLoaded(interstitialAd: InterstitialAd) {
          Log.d(TAG, 'Ad was loaded.')
          mInterstitialAd = interstitialAd
        }
      })
    }
}

4: Add the FullScreenContentCallback below InterstitialAd.load:

mInterstitialAd?.fullScreenContentCallback = object: FullScreenContentCallback() {
  override fun onAdDismissedFullScreenContent() {
    Log.d(TAG, 'Ad was dismissed.')
  }

  override fun onAdFailedToShowFullScreenContent(adError: AdError?) {
    Log.d(TAG, 'Ad failed to show.')
  }

  override fun onAdShowedFullScreenContent() {
    Log.d(TAG, 'Ad showed fullscreen content.')
    mInterstitialAd = null;
  }
}

6: Add showFullAd to MainActivity and call showFullAd in the activity where you want to show it

fun showFullAd(){
    if (mInterstitialAd != null) {
      mInterstitialAd?.show(this)
    } else {
      Log.d("TAG", "The interstitial ad wasn't ready yet.")
    }
}

https://developers.google.com/admob/android/interstitial#kotlin explains how to request interstitial ads. Your code above created a mInterstitialAd variable but needs to still:

Load an ad
Show the ad at a natural stopping point in your app
