I am able to send emails via gmail, but not showing up in sent items and am unable to see my new emails unless I open up my g mail via safari

Are you using the Mail app that comes with iOS ,
or are you using a different email program that you are trying access via a web browser ... Safari, Firefox, Google Chrome,... ?
if not using Apple's Mail app, the only way you can get access to email is to go to your Internet Service Provider's (ISP's) web site and login to your email program (e.g., Gmail) from there, or use an app for your specific email program ... e.g., the Gmail app.

Perhaps your outgoing internet connection is very slow and the mails stay only for a little while in the box. If you recently did set up the mail account on hat device check if it is an STMP server the mail has to go to. You should setup the SMTP server too.

If you reply on an e-mail when you are in the Gmail app, you are working totally online on the Gmail servers. When using the mail app on the Tab this needs to have settings with Gmail to send mail to the Gmail SMTP server to be able to send the mail.
So in the latter case it will be visible on both Gmail and Tab, if you use the Gmail app it is not visible on the Tab.
My solution is to also send the mail to yourself in the BCC (blind Carbon copy) field, so the recipient does not see it and this way you also have a copy yourself.

Have the emails been deleted?
The sent items should contain all of your emails that have been sent unless you have deleted them.

It might be an issue with your SMTP servers. My mom was having the same issues on her iPhone with gmail. Receiving and unable to send. I deleted the gmail account then re-add it. Under the advanced settings in mail confirm the SMTP server is the correct one for gmail. Forget which one it was but you can google it. See if that does the trick for you. Worked for my mom.

Occasionally Google Gmail user may want to reset the password which used to login into the Gmail account via web, POP3 and IMAP as the original password has been forgotten, or misplaced. Gmail credentials integrates and bases on Google Account. So changing the password for Gmail will also change the password for the associated Google Account.

In order to reset and change the password of Gmail and corresponding Google Account with the affected Gmail email address, follow these steps:

1. Go to https://mail.google.com/ (related: other Gmail URLs).
2. Click on I cannot access my account link.

   

3. Click on radio button of I forgot my password, and then click on password recovery page link (or you can go directly to the link above).
4. Enter the username for the Gmail or Google Account in the field provided.
5. Enter the captcha letters as shown in the image on screen.
6. If you never login to the Gmail for the previous 24 hours, a secret question as set in the Google Account will be presented. Answer the question with a correct answer in order to be able to reset the password.

   If you're unable to answer your security question and the account has a secondary email address configured, a link will appear at the bottom of the secret question results page. Clicking on the link will has a password reset email message sent to the secondary email mailbox. After receiving the email, follow the link to reset the password.
   

   If you have login to Gmail in the preceding 24 hours period, the password reset email will be sent immediately instead. Follow the link to reset the password. If you don't have a secondary email address, or if you no longer have access to that account, repeat the steps above after 5 days. At that point, you'll be able to reset your password by answering the security question you provided when you created your account.
   

7. If you cannot remember the answer to secret question, cannot answer the secret question correctly and do not receive password reset email in secondary email account, try to contact Google for help.
