Images

All articles contain visual elements, including featured videos and images. To view an image in a larger format, click the “View Larger Image” link.

Text-to-Speech

Core Concepts: Periodic Table is proud to offer text-to-speech by ReadSpeaker. Text-to-speech helps newer, challenged, or ESL readers by allowing them to “Listen” to article text as it is read aloud. ReadSpeaker works within all supported browsers.

Text-to-speech is accessible in two ways. First, by clicking the “Listen” button at the top of each article section. This opens a small audio player directly on the page, where you can “Listen” to the section text read aloud in either a male or female voice, pause or stop the audio, and adjust the audio speed and volume to your liking.

The player also includes a drop-down menu with access to even more settings, including controls over how text is highlighted as it is read, the ability to scroll pages automatically in synchronization with the text being read, a way to enlarge text as it is read so that it’s easier to see, a page mask that helps readers focus by dimming the browser window except for a resizable band surrounding the text being read, and more. And the menu’s Text Mode option lets you display article section text in a separate window free from distraction, while providing granular control over text characteristics such as type size, color, spacing, and font, including the ability to apply the Open Dyslexic font designed to mitigate some symptoms of dyslexia. Finally, the menu gives you the option to download an article section’s audio as an MP3 file directly to your device.

In addition, ReadSpeaker integrates with Google Translate to provide text-to-speech in 13 languages besides English. When you choose Arabic, Chinese, French, German, Greek, Hebrew, Italian, Japanese, Korean, Polish, Portuguese, Russian, or Spanish in the Select Language drop-down menu at the top-right of every article section and then click “Listen”, the player seamlessly reads the translated text as it appears on the page aloud.

The second way to activate text-to-speech is by selecting text in an article—either a word, sentence, or entire paragraph—and clicking “Listen” in the popup menu that appears. The popup menu also includes a dictionary for quick text definitions and the ability to translate selected text into multiple languages.

There’s a Help button in the ReadSpeaker drop-down menu, which includes topics that should answer any questions you have about the text-to-speech feature.

Note: In articles devoted to individual chemical elements, text-to-speech is not active on the first section of each article, but is available in all subsequent sections.

Text Translation

The text translation feature provided by Google Translate allows users to translate article text into more than 100 languages, including Arabic, Chinese, French, German, Greek, Hebrew, Italian, Japanese, Korean, Polish, Portuguese, Russian, and Spanish. Just select the language of your choice from the drop-down menu at the top of each article section.

Enhanced Text Visibility

Enhanced text visibility, a way to enlarge article text so that it’s easier to see, is available in ReadSpeaker, the text-to-speech feature available in all Core Concepts: Periodic Table articles. To turn on enhanced text visibility in an article, click the “Listen” button at the top of each article section, click the menu icon in the upper-left corner of the ReadSpeaker player, and select Enlarge Text.

Print

In all articles, the Print button in the left navigation bar will open a new window that allows you to either print the current section of the article you are viewing or to print the entire article. Images and the article citation will be printed.

You can also print the current section by going to your browser’s File menu and selecting the Print option. If you have difficulty printing, please check your printer setup.

Click the Email button in the left navigation bar to email an article to yourself or someone else. When you click this button, a new window containing a form will open. You must enter your name, your email address, and the recipient’s email address. If you wish to send the article to yourself, put your own email address in the field for the recipient’s email address.

You may also enter an optional greeting/message to the recipient and attach images from the article to your email if you wish. The article citation will also be included in the email in MLA (Modern Language Association) format, APA (American Psychological Association) format, or Chicago Manual of Style (16th edition) format.

Email messages, in rare cases, may take up to an hour to be received after they are sent. If you have trouble receiving email sent from the site, please check your email junk mailbox or filter, or check the spelling of the email address to which you are sending.

Citation

Click the Cite button on the left navigation bar to use the NoodleTools citation generator. You can also see the article citation in MLA (Modern Language Association) format, APA (American Psychological Association) format, or Chicago Manual of Style (16th edition) format.
